It May Help You on Your Quest

A character is handed (or idly picks up, or discovers in his possession) a seemingly useless item of junk. This can happen fairly early in the story -- in The Heros Journey, it's one of the first steps.

The item in question later becomes important to resolving some major or minor obstacle moving the characters forward. Or the character thinks it will, anyway. Or the character, if handed it, cherishes it as a gift. (Or the character is a pack rat.)

Items of this sort are a certain form of Chekhov's Gun.

Especially common in Adventure Games from the 90s, from whence the name was derived.

A Plot Tailored to The Party involving items instead of personality or skillset typically revolves around these.

This is similar to when a character learns a seemingly useless skill or fact that will be needed later on, see: Someday This Will Come in Handy. If an item is elevated to Plot Coupon status, it is because You Will Know What to Do.

Popular items include paperclips and the like, as well as jewelry, perhaps because of its nominal resale value. It could be magic beans, a piece of moldy cheese, etc. If an item is conspicuously clickable, compare Notice This. See also Orphan's Plot Trinket.

If your entire starting kit consists of these items, you may be asked to defeat evil With This Herring.

Common enough that subversions are notable when the item will in fact turn out to be useless junk. Or immediately useful.

A Genre Savvy character may fob off an otherwise useless Clingy MacGuffin (or just get the hero to take out the trash) by uttering the words "Take this... it may help you on your quest."

On the other end, their genre savvy may lead them to grab everything they can so as to be ready for every conceivable challenge or obstacle.

An unusual variant is when the giving character says, "You'll need this more than I do." - common amongst elders who have advanced beyond the need for an item. Compare Grail in The Garbage. Not to be confused with Vendor Trash, which is only valuable in large quantities. If the item turns out to have sentimental value, it is a Memento MacGuffin.

When the character's whole objective is to obtain or deliver an item, it is a Plot Coupon.

Anime and Manga

 * Definetely Inuyasha. The main character's battle-happy brother Sesshomaru receives a sword that resurrects people. He begrudgingly carries it around and eventually resurrects Rin as a test to see if the sword works. The sword has a catch: it can only resurrect a person once so it can't save the people Sesshoumaru actually wants to save. It turns out that he needed Tenseiga and the lessons Tenseiga forced him to learn to be able to finally achieve his desire (a combat sword of his very own that could match his vast power, the idea being that only a compassionate heart should wield great power otherwise that power would be grossly misused).
 * In the penultimate episode of Mazinkaiser Boss gives Kouji a resistance bar. Kouji uses it immediately to smack an Iron Mask Soldier. Then in final episode Mazinkaiser's control stick breaks and Kouji uses the bar to replace the broken part, letting him pilot Mazinkaiser again.
 * The Orihalcon Statue in the first arc (both novels, anime, and manga) in Slayers, which holds a powerful, magic-enhancing stone fragment. Lina happened to stumble across it on a treasure hunt, but the priest Rezo seeks it to cure his blind eyes.
 * Later on in the novels, there's the Blast Sword. Because he loses the Sword of Light for good in this version, Gourry needs a new one. He and Lina find a rusty old sword, and during the battle with Dynast Grausherra, it reveals itself as the Blast Sword, which is even more capable of fighting demonic beings than the Sword of Light.

Comic Books

 * In Asterix in Britain, before setting out on the journey to Britain, Asterix takes some herbs from the Druid Getafix who says "Take some if you like." These herbs are eventually found out to be
 * Not long after Final Crisis, it's revealed that Darkseid cloned Batman several times. When the clones went crazy, they were all killed, except for one, just in the off chance that Darkseid ever needed a spare Batman corpse. Which he used to fool the world into thinking Batman was dead, so I suppose it's a good thing he cleared out room in his fridge for a spare Batman corpse, eh?

Fairy Tales

 * The beans from Jack and The Beanstalk.
 * He traded a cow for them, though.
 * Found in a Norwegian folktale about a princess who always had to have the last word. Three brothers are off to try their hand at winning the princess; the youngest is mocked for carrying around every piece of junk he finds. Youngest brother manages to stun the princess into silence by using the junk as props ([brother holds out goat horn] "I've never seen the like!" [brother gets out other goat horn] "Here you see the like, Princess.") and they live happily ever after.
 * In Mercer Mayer's version of "East of the Sun And West of The Moon", the heroine meets a Plant Person of the forest, a Giant Fish of the ocean, and the North Wind, each of whom gives them a gift which she needs to use in order to defeat the Troll Princess: a bow and arrow from the king of the forest, a fish scale, and a tinderbox. In the last case,.

Film
"Tia Dalma: Land is where you are safe, Jack Sparrow. And so you will carry land wit' you.
 * In Pirates of the Caribbean: Dead Man's Chest, Tia Dalma gives Jack a jar of dirt. This isn't surprising, since the Pirates films seem to be influenced by Lucas Arts' Adventure Game series Monkey Island, which plays this trope..

Jack: Dirt... This is a jar of dirt.

Tia Dalma: Yes...

Jack: Is the jar of dirt going to help...?

Tia Dalma: If you don't want it, give it back.

Jack: No!

Tia Dalma: Then it helps."


 * If Davy Jones can't set foot on dry land... and you pour the dirt out around you... Or, hell, even around him... A bucket of water negates any good that the dirt can do under the best circumstances.
 * The everyday items in Paycheck. Rare film example of a plot setup involving the character collecting otherwise useless everyday items, Justified Trope in that the character knew exactly what was going to happen in the future and when. Although why such a security conscious company would allow him, with their knowledge, to take a key card with him is anybody's guess.
 * Miss Spink and Miss Forcible know exactly what Coraline needs... a piece of rock with a hole in it. It helps. Well, they are good for bad things. Or is it lost things...?
 * They were just Genre Savvy enough to recognize the utility of a Self-bored Stone.
 * In the Ewok Adventure TV movie, Mace is given a seemingly useless rock by Chief Chirpa. He discards it, but Wicket picks it up and gives it back to him, to Mace's dismay. Later when the group is trying to find the entrance to the Gorax's cave, Mace tries to use his blaster to make an opening, but it fails to destroy the rock. However, when he breaks open the little innocuous rock given to him by Chief Chirpa, a little arrowhead falls out and zips under a nearby boulder, which is revealed to be a secret entrance to the cave.
 * Almost every James Bond movie had Q give 007 a stack of gadgets, which he would use once each in the course of the film. These would usually be unveiled in descending order of firepower and perceived uselessness, with the latter always proving to be the most essential, presumably because his captors wouldn't think to take it from him. Much more advanced and bizarre technology in Q's lab would be pooh-poohed as not ready for prime time.
 * At the beginning of each episode of the James Bond Jr animated series, the Gadgeteer Genius would give Bond three very use-specific items. Almost always he would use those three items in the same order they were given...
 * Done rather poorly in Troll 2, when Grandpa Seth hands Joshua a double-decker baloney sandwich, saying "take this, and only use it when you really need it". The last 5 minutes of the film may not be a good time to introduce a vital Chekhov's Gun.
 * Another iffy example happens in Van Helsing when the monk-inventor sidekick introduces the hero to a seemingly vulgar stone that can produce a sudden burst of solar-like light. The monk-inventor insists he doesn't know why it could be helpful, despite knowing that they are going to travel to Transylvania to fight vampires who are vulnerable to day light, then says he is going to take it anyway. Three guesses about what specific item they use to escape a palace filled with vampires at night later on.
 * The Man Who Would Be King: In the glory days of the British Raj in India, ex-soldier Peachey Carnehan (Michael Caine) steals a pocket watch from a well-dressed white man (Christopher Plummer as Rudyard Kipling) at a train station. Peachey sees the watch fob is a Masonic emblem and, being a Mason himself, 'has' to return the watch, hopefully without giving away his thievery. He does (or thinks so) and thus meets Kipling. Later Peachey and Daniel Dravot (Sean Connery),also an ex-soldier and Peachey's fellow 'gentleman-of-fortune', meet with Kipling and tell him of a grand adventure they are about to embark on. Later still, as they leave for this adventure, in an impulsive gesture Kipling gives the watch fob to Dravot. It later saves their lives.

Literature
"What's this? a vial. And what magic is in it to make it glow so? Handy, this thing..."
 * The Harry Potter series in general features this.
 * The Time Turner.
 * In Harry Potter and the Deathly Hallows, each child gets a pleasant but seemingly useless gift (a Snitch, his Put-Outer, and a book of fairy tales) from Dumbledore with cryptic hints. Each proves critical to their quest. Justified because   he can't outright tell them. For a similar scenario on film, see Paycheck.
 * Galadriel's gifts in The Lord of the Rings. Her gift to Sam? A Box Of Dirt with a seed in it.
 * Galadriel specifically says it won't help Sam on his quest, but when he gets home. Given his vision in the Mirror, she has a fair idea of how it will be used.
 * Arguably, Galadriel's little phial, too. The movie version implies that Galadriel knows it will be useful against Shelob, but the book, less so.
 * Moreso in the animated The Return of the King, where the phial just shows up in Sam's pocket.

"He crawled along for a good way, till suddenly his hand met what felt like a tiny ring of cold metal lying on the floor of the tunnel. It was a turning point in his career, but he did not know it. He put the ring in his pocket almost without thinking: certainly it did not seem of any particular use at the moment."
 * The Mithril chain mail that Bilbo gives to Frodo. He was really right.
 * The Hobbit: "What have I got in my pocket?"'' he said aloud.


 * In Percy Jackson and The Olympians the eponymous character is given a pen and told only to use it times of great need. It helps.
 * He then proceeds to whip it out at any possible time whatsoever, probably because
 * In the book, "Key to Rondo"
 * In Star Wars Legacy, Cade Skywalker is handed R2-D2. He is not impressed.
 * As she leaves for a boat trip, Martine of Dolphin Song is given a plant by the old woman who's been teaching her about bush magic. everyone teases her about it, until it proves to be the cure (the only cure on hand) for Man o' War stings. The best part is, the woman told her later that she just wanted it out of her garden.
 * In The Phantom Tollbooth, Milo is given gifts by many of the people he meets, and they all come in handy when he is facing the demons who live in the Mountains of Ignorance.
 * The Sirens of Titan features an interesting twist. The main character's son picks up a random piece of scrap metal during a factory tour on Mars. It becomes his lucky piece and he carries it with him everywhere for the rest of the book until they arrive on Titan itself. Turns out, this little piece of scrap is the replacement part the alien observer has been sitting around waiting for since before the dawn of humanity. It seems all of human history was guided (and perhaps even BEGUN) by his species remotely just to bring him this small piece of metal so he could continue his mission (which it turns out is just to say "Hi" to whoever lives on the far side of the universe). It's a bit of a downer realization, until one considers that with this delivery/quest complete, perhaps humanity will be free to pursue its own destiny.
 * In Jim Butcher's Spider Man novel The Darkest Hours, Spider-Man asked Doctor Strange for his assistance in dealing with the Ancients, three malevolent beings related to Morlun(from the J Michael Straczynski run). Strange refused, stating that doing so would undo the cosmic balance. He did arrange for his manservant Wong to prepare Spider-Man a sack lunch...which contained, along with a ham sandwich, three small stones which could be used to transport someone to an uninhabited dimension. After Spider-Man defeated the Ancients, Strange asked Wong what had happened to the stones, pretending not to know anything about their use.
 * Subverted most effectively in Brandon Sanderson's Mistborn trilogy -
 * Subverted in Katherine Mac Lean's Missing Man, where a guru gives George (the protagonist) a quarter, saying "I can see into the future a little. In two weeks if you don't have a quarter you'll probably die", and "Tape it to your skin and forget you have it". In fact, the quarter does become (hypothetically) useful, . . . except that.
 * In Whispering Nickel Idols, Garrett brings a bucket of kittens to Belinda's mob party, thinking he can get rid of a few by giving them away. (Morley lampshades how unlikely this is to work, but Garrett really doesn't want a bunch of cats in his house.) As it happens,.
 * Ford Prefect's penchant for towels arguably counts. He insists to Arthur that they are useful in all kinds of situations.
 * Common in live-action adventure games from the Dream Park series. Kevin's gift of a soot-covered rag in The Barsoom Project is a good example.

Live Action TV

 * Rather cruelly inverted in an episode of House, where they spend an entire episode looking for a cause for a young boy's ailment, only to discover that . Previously unrevealed to the audience, it had been randomly picked up by his father, a scrap dealer, and given to him as a Memento MacGuffin to remind him of his roots.
 * Parodied on Garth Marenghi's Darkplace, when ghostly Scots invade Darkplace Hospital: "What's this?" "Something that might come in handy."
 * Played fairly straight in Merlin in "The Eye Of The Phoenix" when the Fisher King hands Merlin the waterglobe and says "When all seems lost, this will show you the way."
 * Happens on Tracker when Mel finds both her grandmother's diary and the strange triangular object. She finds it a bit odd but dismisses it and nails it up as a decoration, and it's only later that the writing on it is ID'd as Vardian and they learn that it's the key to the underground vault, and that the diary's poetry was another key clue.
 * Estate of Panic: The most successful contestant in the second of three rooms usually received an item that might have helped them in the third. For example, in the first episode a contestant was given a screwdriver, but had to figure out where to use it (on the A/C vents) to earn the extra money.

Music

 * At one point in Revolution #9, a voice says "Take this, brother, may it serve you well." Is it Ringo? It sounds like him.)

Opera

 * In Richard Wagner's Siegfried, after Siegfried kills Fafner, he can understand the forest bird's song telling him to take the ring and helm. He doesn't know what they really are, but it keeps them out of the hands of Alberich and Mime. (Too bad that the ring is an Artifact of Doom...)

Radio
"Grytpype-Thynne: Now, here's a screwdriver, a blindfold and a cucumber.
 * From an episode of The Goon Show:

Neddie Seagoon: Cucumber?

Grytpype-Thynne: You've got to eat, haven't you?

."

Video Games
"(later) "HEEEEEEY! DON'T FORGET YOUR FISH!""
 * All the old Lucas Arts adventure games have this. If you can pick it up, no matter how random and useless it seems, you will at some point need it. Unless it's a Red Herring. And sometimes even then, as The Secret of Monkey Island has proven.
 * An interesting case occurs in Escape From Monkey Island in the Swamp O' Time. Guybrush meets himself in the future, who gives the present-Guybrush several items and holds a conversation with him. Shortly after, present-Guybrush ends up on the other side of the encounter and must follow the exact same routine as before in order to avoid a Temporal Paradox and restart the area. One of the items is a pistol, which makes Guybrush excited to finally get one, only to have to give it away soon after. The items themselves are a part of an Ontological Time Loop, as they have never been created.
 * Monkey Island plays with this one. At one point in the first game, you can pick up a staple remover, which Guybrush remarks will probably come in handy. Like almost everything else you find, it is seemingly useless, until:
 * One may use it immediately against a yak with wax lips.
 * Not to mention a Rhinoceros' toenails; probably the same Quarrelsome Rhinoceros you hypnotized earlier.
 * The staple remover can also be combined with the flint to blow up the dam on Monkey Island. Since this puzzle can be solved with the spyglass and the sun, it makes at least one set of items (or resulting scenery) useless.
 * "A rubber chicken with a pulley in the middle...what possible use could that have?"
 * "That thing your aunt gave you which you don't know what it is," from The Hitchhikers Guide to The Galaxy the Text Adventure game.
 * The thing in question is a Clingy MacGuffin which doubles as a Bag of Holding. You can't get rid of it permanently, no matter how hard you try, and you can store things in it as well. It's very useful, but these miraculous properties are never hinted at in the game itself - you have to discover them for yourself.
 * Every Infocom game includes at least one of these. The best is the piece of braided black string in Zork 2, which seems completely useless at first, but turns out to be.
 * The two Discworld games, where there really are totally useless things to collect, albeit not many, making them more Red Herrings.
 * There are items like this all over the place in Alone in The Dark, e.g. an Indian cover, a heavy statuette and others whose use isn't quite obvious at the beginning.
 * In Brain Dead 13, both times while trying to get away from the witches, Lance picks up an eyeball hanging on a rack for no discernible reason whatsoever. At the end of the game, he gets the idea to tie the two eyeballs together like a bola in order to stop a boss, but that still doesn't answer the question of why he picked up the eyeballs in the first place.
 * The moldy cheese you need the fishhook to retrieve in King's Quest V. What sort of monster goes around collecting moldy cheese?
 * Every King's Quest game has at least one Wizard Gift. The guide even says "If it's not nailed down, take it. If it is nailed down, check for loose nails."
 * Not just King's Quest, every Sierra game has one of these. At least. Actually, it seems like an Adventure Game trope.
 * King's Quest I: pebbles, a carrot and that silly bowl you find in the middle of nowhere
 * King's Quest II: a wooden stake and a random piece of cloth
 * King's Quest III: oh so many potion ingredients; virtually everything you can pick up is required to brew a magic spell
 * King's Quest IV: a book of Shakespeare quotes and a peacock feather
 * King's Quest V: a stick, an old boot, a pie, let's face it, over half of the inventory items here qualify due to Guide Dang It puzzle design
 * King's Quest VI: an empty bottle that turns out not to be empty, a shred of paper, and a rabbit foot
 * King's Quest VII: A rubber chicken, an ear of corn, and a hair comb (Valanice) An old sock, a severed foot, and a sweet-smelling flower. (Rosella)
 * Space Quest 1: a plant, a rock and an undefined "gadget"
 * Space Quest 2: a silly puzzle and, again, a rock
 * Space Quest 3: the orat-on-a-stick, and a cereal decoder ring
 * Space Quest 4: an energizer bunny
 * Space Quest 5: a banana and a packet of space monkeys
 * Space Quest 6: "Also, you look like you could use this fish."

"Roger: I finally got rid of that fish!"
 * This happens repeatedly throughout that game. Guess it's a good thing that the fish


 * Leisure Suit Larry 1: a glass of whiskey
 * Leisure Suit Larry 2: a flower
 * Leisure Suit Larry 3: soap-on-a-rope...
 * ...Yup, definitely an adventure gaming trope.
 * There's a piece of moldy cheese you had to pick up in the  Blade Runner adventure game, too. You have to Pixel Hunt to get it. Semi-justified in that cheese was an illegal substance in the story. (Yes, they made a Blade Runner Adventure Game. It has 13 alternate endings.)
 * Zelda: The trend in the series, since at least the second game, is that you will always get what you need to complete the next dungeon either in that dungeon, or right before it. This can become Egregious at some points, like the trope picture. How lucky is it that you found that item right before flipping over blocks and pots from a short distance away became a vitality important ability? It's sometimes justified by the dungeons being carefully laid out trials, but just as often it isn't brought up. Did whoever designed the fire-temple in The Legend of Zelda Ocarina of Time know that the switches would become rusted over, and that's why they left a hammer capable of pressing them for you to find, or was it just a coincidence?
 * "It's dangerous to go alone! Take this!" Sure is handy that some old geezer who is giving away the game's most essential item for free lives right where Link happened to begin his quest. Although the rest of The Legend of Zelda is much less conveniently arranged.
 * When replaying Silent Hill 1, you find a device in the 7-11 lookalike that is of no use unless you're at certain locations (e.g. the rooftop of the oxidised Midwich Elementary) through which you get the Alien ending and a raygun for the next replay.
 * During the main story, Harry comes across the elderly witch Dahlia Gillespie, who assumes The Mentor role and gives Harry two items: a rather sensible key to a locked drawbridge, and a more bewildering puzzle-box device, along with the cryptic explanation that "these will help you". It later turns out that.
 * Silent Hill 4: The Room doubly subverts this trope with the 'Shabby Doll', kindly offered to you by Walter Sullivan halfway through the game. Not only can you not use it, nor does it help you out in any way, but stashing it away in your inventory results in . Players aware of this simply refuse the 'Shabby Doll', but those who aren't will accept it, because there is no reason to not take it.
 * A very minor example occurs in Mass Effect if you choose all the paragon interactions with the Asari Consort. She gives you a seemingly worthless trinket that you can later use on another planet to unlock a cache of valuable equipment.
 * In Taiyou no Shinden Asteka II (a.k.a. Tombs and Treasure), you get the lighter from the first room in the game, and it can't be used for anything until the last room in the game, where it's necessary to complete the game.
 * Final Fantasy I: You're given a Lute by Princess Sarah after you defeat Garland. This item does absolutely nothing until the final dungeon, where you play it to break a seal and move on. Remakes show your lead character playing it. The song? The Prelude.
 * In Final Fantasy IV, if you talk to Yang's wife at a certain point, she will give you a spoon. This turns out to be a thrown weapon, and
 * Earlier in the game, you get the FRYING PAN OF LOVE, no mere spoon, which is also, which is an even better throwing weapon (the spoon is in later versions replaced with a knife).
 * In Ratchet & Clank: Tools of Destruction, The Plumber hands Ratchet a 3 3/4 Centicubit Hexagonal Washer saying "you never know when you'll need it." This item is utterly worthless throughout the game. As it turns out,
 * In Lunar Silver Star Story Complete, you have Alex's ocarina from the beginning. You won't really need it until the very end, when you have to.
 * The 'Wand of Nagamar' in Kingdom of Loathing has no combat or utility value (though the combat messages could be entertaining.) However it's required on the final Council Quest
 * The game has a considerable (and sporadically growing) number of such items, varying in degree of apparent uselessness, and has slowly begun to add skills of this type (such as the Disco Bandit skill "Gothy Handwave", which is Exactly What It Says On the Tin - and unlike other dance skills, does exactly what it does in real life).
 * Very few examples are actually handed to the player with the accompanying dialog, the rest of them Randomly Drops without drawing attention to their significance. The Amulet of Plot Significance which drops on the Penultimate Fantasy Airship is one subversion, but the Cid-like Captain Ersatz on the same ship gives you two items critical to completing that quest and The Very Definitely Final Dungeon.
 * Not really useless in value, but the wedding ring in Tales of Monkey Island is given to you in Episode 2 and proceeds to uselessly sit in your inventory..
 * At the start of Final Fantasy XII, the main character Vaan breaks into the Palace of Rabanastre to 'liberate' the treasure within from the imperials. However, thanks to well-times distractions, he only manages to steal a shiny rock. This turns out to be the Dusk Shard, which falls into enemy hands when Vaan is captured. In a subversion, it's the villain who nearly wins because of it - he attempts to use it to power a giant airship.
 * Every game of Indiana Jones and his Desktop Adventures (an adventure game where the world and puzzles are randomly generated each time) should begin with Marcus giving you a briefing and giving you "something to get you going" - usually a priceless ancient artifact which inevitably turns out to be just the thing a NPC needs.
 * Many adventure and RPG games condition pack-ratting behavior as an inventory management pressure, especially if there are inventory limitations and/or economic necessities. Not all games give clues whether the items are useful for problem-solving, or at least for uncovering Easter Eggs, or just Vendor Trash or completely dead weight. Recently the games have gotten easier by simply making the 'Handy' things undroppable/unsaleable, rather than more intuitive in their problem-solving application.
 * In the first Mata Nui Online Game, after the Po-Koro event, as a reward for helping the town, you are given an item, the "Po-Koro chisel" which seems to have absolutely no use, surprising in a game where every single item serves at least some purpose in one way or another. Flash-forward to the ending cutscenes of the game where Takua is fleeing from, and he discovers a device with an indentation that bears a staggering resemblance to the chisel. If you can't guess what happens next, you haven't been paying much attention.
 * One game that averted this was the original Maniac Mansion game, which, due to having multiple characters and multiple endings, had many items that were worthless if you had the wrong party. It also had items that were completely worthless no matter what, such as the chain saw, which had no fuel.
 * Interestingly, the sequel goes back to the traditional tactic of not only having every single item be used at least once, but if the item is small enough to be passed through time, it will be needed in another time.
 * The only item that's never used is the hubcap....and you can not pick it up.
 * Standard policy for adventure games is that if it's not nailed down, take it, you'll need it. If it IS nailed down, find a way to remove the nails and take it. And take the nails too. Many, many early adventure games punished people for following this advice before realizing that it was a bad idea. For example, in Uninvited, picking up a certain seemingly important gem results in being demonically possessed about three turns later. Whoops.
 * Played with a bit in Starcraft II 's first campaign, which has protagonists Jim Raynor and Tychus Findlay (along with their army) gathering seemingly benign Xel'naga artifacts for the Moebius Foundation early on in the plot. While the fanatic Tel'darim put up quite a fight for it, and the Hyperion's resident scientist Egan Stettman detects some weird readings from them, none of them suspected that the artifacts were actually the
 * Everything about Marle's pendant in Chrono Trigger. It starts out as a MacGuffin, but once you go to Zeal, it's very important.
 * The Dynamix adventure game Rise of the Dragon has one character give you the following items all at once:
 * A shiny rock, for luck. Useless.
 * A tome of "Ancient Wisdom." Every page reads "Don't Worry, Be Happy"
 * A fortune cookie with gibberish on it.
 * And, "in case all else fails, some body armor."
 * In Final Fantasy VIII, if Squall talks to Cid just before leaving for his first SeeD mission, Cid presents him with an old lamp which he says is a cursed item but might come in handy. The lamp has the Guardian Force Diablos sealed inside it.
 * In Spellcasting 101, there is a book that is so good you can't put it down. Literally. Once it's in your inventory, you can't drop it.
 * In The Orion Conspiracy, LaPaz will give Devlin keys to open the cupboard in Danny's room. Also, Ward will give you a rotten biscuit to spite you later on. In both cases, the items are immediately useful in some way.
 * Green Moon is full of items which seem initially useless but turn out to be necessary for spells or potions.
 * Parodied in Pokémon Black and White: the post game begins with coming to your home to ask for help  He then gives you a Super Rod (a fishing rod), and the player character's mother asks what help a fishing rod would be. After thinking for a minute he admits that it would be no help whatsoever.
 * Also seems to show up in Pokémon Gold and Silver and the remakes. The player's mother saves some of the money they earn and randomly buys items. She'll always say "I'm sure you'll find it useful" or something like that when she calls to tell you.
 * In Radiant Historia, the main character, Stocke, is given a seemingly useless book by his boss at the beginning of a mission.

Web Comics
"Uncle Sparky: I shall give you a half empty pizza box and a bag of garbage to take to the curb. May they be of aid to you on your journey."
 * In Order of the Stick, Celia gives Roy a magical talisman that, when broken, would summon her to save Roy if he was in danger.
 * Even more so,
 * And just to subvert further, the reason
 * Also, during an early adventure, Elan picked up a magic belt that can turn the wearer into the opposite gender. Some time later, Roy needed a way to sneak past the enemies without his weapon and Elan showed him the belt.
 * In Wicked Awesome Adventure, Rhys picks up a back-issue piece of Saucy Literature (centerfold: Sambal Kacang) that is a surprisingly useful item.
 * Other strange but useful items include a red rubber stopper, a traffic cone, and a mouse (with furniture).
 * Gunnerkrigg Court: Annie got a "beacon" from Eglamore way back in chapter 20 (November/2008). As of chapter 36 (December/2011), it still hasn't been used. If that's not an example of this trope, it's either a subversion or a very long setup for a Brick Joke.
 * Problem Sleuth carries his precious cargo through the whole comic/game: four pieces of candy corn.
 * Parodied in the Dragon Tails RPG arc, in the same strip as But Thou Must, nonetheless. Uncle Sparky, the dragons' slobbish uncle, offers the heroes some help.

Web Original
"Jack: I've got a jar of dirt!"

 * Tends to happen a lot in The Questport Chronicles. During Year Two, the heroes find a bunch of junk, including an old spell, while searching for a different Plot Coupon; the spell becomes vitally important to retrieving the next Plot Coupon.

Western Animation

 * Subverted in an episode of Family Guy. After Quagmire has an affair with Cleveland's wife, Cleveland's swears revenge. Quagmire hires Mayor Adam West as a guard, but after failing to keep still, West decides to leave while giving Quagmire a banana and telling him "When the time comes, you'll know what to do." Later, when Cleveland is chasing him, Quagmire throws the banana... and it does nothing.
 * The way the scene is set up to Invoked Trope the classic banana peel gag to viewers, but Quagmire forgot to peel the banana before throwing it.
 * One episode of Darkwing Duck is made up of a long string of characters literally saying "This could come in handy some day." It's an aged Darkwing telling his supposed origin story, and everything from his gas gun to his martial arts skills is given to him with this note from the repeated giver. And damned if they don't all get used in sequence in the course of about a minute.
 * As a parody or tribute to James Bond, Totally Spies uses the exact same "three gadgets that each get used once" shtick.
