I've Never Seen Anything Like This Before

""Whoa! This place looks just like... it reminds me of.. this is just like that time I... hm. I don't think anything like this has ever happened to me before...""

- Jan Jansen after seeing Hell, Baldur's Gate 2

If one of the people questioned during the investigation of a Monster of the Week is a policeman or a marine or a scientist or some other person who was on the job when they saw the thing or event, there's a good bet they'll say some variation on this line: "I've been a biologist for thirty-four years, and I've never seen anything like this before", "You see some strange things on this job, but I've never seen anything like this before", etc; much of the time the line is spoken in such a way as to suggest that the speaker will be haunted and traumatized by what they saw to the end of their days. The message is clear: if it's got the professionals spooked, you must be onto something.

It can also be used as a form of As You Know, or more accurately, "As You Didn't Know." In a setting where everything is unfamiliar to the viewer, special mention needs to be made of things that are unfamiliar to the characters in the setting.

Anime

 * Dragonball Z - Any time that a fighter- hero or villain- attains a new level of strength. "I've never felt a power anything like this!!"
 * Expressed constantly by the various sources of technobabble (mainly Ritsuko and the Bridge Bunnies) in Neon Genesis Evangelion. A promo for the show's brief stint on Toonami actually contained this exact line.

Film
"Hot Rod: Doesn't this remind you of anything, Kup? Kup: Nope. Never seen anything like this before."
 * Played straight in the first X-Men film. When they are examining Wolverine's x-rays and Jean is telling everyone about his adamantium covered skeleton, Xavier ominously says, "Experimentation on mutants isn't unheard of, but I've never seen anything like this before..."
 * Used half-seriously in Transformers: The Movie, where the old Autobot warrior Kup had continuously been playing The Munchausen, comparing current situations to things that happened in his old war days. But when he sees Unicron attacking Cybertron, he's left speechless:

"Earl:: Hey, Rhonda, you ever hear of anything like this before? Valentine (sarcastic): Oh, sure, Earl, everybody knows about 'em, we just didn't tell you!"
 * Inverted in the movie Tremors, in regards to a giant burrowing worm-monster:

"Angela: So, you've never seen anything like this before? Lawrence: No, I have never seen anything like this before...mostly because I'm a vet."
 * Invoked, then subverted, in Quarantine:

""Jeweler, you've failed!""
 * Later played straight (or possibly double-subverted) when the virus turns out to be.
 * In Ghostbusters, New York's police commissioner claims "to have seen every form of combustion known to man", but the destruction of the containment unit (and the firehouse with it) "beats the hell out of [him]".
 * The Jeweler in Help!! says the trope name exact after breaking all his tools trying to Ringo's ring.

Live Action Television
"Anya: Yes, 'cause it seems like we're always dealing with creatures from outer space. Except that we don't ever do that."
 * Buffy the Vampire Slayer:


 * Parodied in Get Smart. When confronted with something like an arrow the size of a rocket, Max would say "That's the second largest (arrow) I've ever seen!"
 * This gag was also used frequently in the Monkey Island games. The most famous is probably "That's the second biggest monkey head I've ever seen!" Escape from Monkey Island had the line "That's the second biggest... no, wait, that is the biggest conch shell I've ever seen!"
 * Sam & Max: Moai Better Blues features a Shout-Out to the above gag, in the form of Max proclaiming "That's the second-biggest Bermuda Triangle I've ever seen!"
 * Commander Keen 6, Aliens Ate My Babysitter does this too with the "Second Biggest Sandwich I've ever seen!"
 * Sent up in the first episode of Kim Possible in which "Team Go" appeared: "That is the second biggest flamingo I've ever seen."
 * The TV show The Zack Files had a character who kept trying to scientifically explain and document the weird paranormal stuff that constantly happened around Zack Greenberg. His catch phrase, upon seeing whatever freaky event was transpiring, was "It's like nothing I've seen before!"
 * Used oddly straight, albeit without the stock phrase, in an early episode of CSI: the coroner enthusiastically describes the condition of a corpse as "Weird. Like I may use her in a lecture weird." Turns out the body had been frozen, which doesn't really seem strange enough to justify the reaction.
 * Parodied in Whose Line Is It Anyway?, in which Colin makes a Running Gag of saying this at the start of every single Newsflash game.
 * Also comes up once as "The good news is, we're naming a disease after you!"
 * Given the premise of the show, this line comes up at least once an episode in The X-Files.

Newspaper Comics

 * Parodied in The Far Side. Two Eskimoes see two creatures coming out of a spaceship; creatures that look exactly like the Theme Park Version of a tall cactus, with arms and legs added on. One of them exclaims, "They're like nothing I've ever seen!"

Theater

 * "We've seen shit, but never like thiiiiis!"

Video Games
"Alex Roivas: Yes, it's him... He's wearing our family ring.  I don't understand! Why are you showing me this?! Can't you check dental records or something? What is wrong with you?! Inspector Legrasse: In my 30 years on the force, I've never seen anything like this... and no, we can't check dental records! There's... there's no head."
 * Used straight at the beginning of the indescribably scary game, Eternal Darkness, when the police detective describes what's happened to the female protagonist's grandfather...


 * Also used when a player-controlled medical doctor autopsies the various monsters he encounters.
 * Subverted when Peter Jacob brings the Essence he found to the mansion; Edward Roivas has seen something like it before (the one Edwin Lindsey brought him 2 years earlier), and says so.
 * Anyone who tries to read the protagonist's fortune in the Baldur's Gate series gets spooked.
 * And to put the page quote in context, Jan Jansen is the resident Cloudcuckoolander Munchausen with a tangenitally related story for every occasion. Him being stumped produces a rash of comments form the other party members that the end must be nigh.
 * Quoted in Persona 3 by Mitsuru, the team's leader and current Mission Control, who gives a subdued "I have never seen anything like this" as they start their battle with the Priestess, one of the Arcana Shadows. This is used to reveal to both the newer members of SEES and to the player that, although the group's been fighting the Shadows for ten years, this is something entirely new to them.
 * Bill of Left 4 Dead says the trope name when examining zombie corpses in the intro. He takes it as proof that "they're changing".
 * In Sword of the Stars, when you encounter a Silicoid Queen in combat, your ship personnel may say something to this effect. It gets silly when they say it again in subsequent encounters.
 * In Kingdoms of Amalur Reckoning, Argath the Fateweaver questions whether you actually exist or are just an alcohol-induced hallucination when he is unable to see your Fate in his cards. As far as he knows, no one should be able to exist outside of the Weave of Fate. A bit later in the game, Argath exclaims "What are you!?" in bewilderment and fear.

Web Comic
"Jones: The way he has distorted his body...I've seen similar, but nothing quite like that. Headmaster: Coming from you that disturbs me greatly."
 * One wizard (or such) comments this when seeing the Monster in the Darkness (then without darkness, but invisible for the reader) in the prequel "Start of Darkness" of the webcomic Order of the Stick.
 * Gunnerkrigg Court has a version of this, after the meeting with Coyote and Ysengrin, about the latter's new Green Thumb (and arm, and bipedalism, and who knows what else):


 * Sluggy Freelance: I've never seen a universe so ... deliberate."
 * The webcomic Hero In Training has a variation, when a character who outlives universes said that he only has seen the current situation three times in his life.
 * Averting this is a running gag in The Pig's Ear, with resident Deadpan Snarker Cyril T. Wizard having "this is the third strangest/worst/whatever X I've ever seen" as his Catch Phrase. The first time we hear him say this is when, prompting Cyril to remark, "That is the third strangest thing I've ever seen in a pub toilet." It's probably best not to speculate upon what the first two might have been.

Web Original
"Goku: I'm gonna deck you in the schnozz!"
 * In Dragon Ball Abridged, Freeza keeps track of every Badass Boast and tallies every line of Heroic Speech he hears. He's heard everything, and we do mean everything, at least ten times, until he meets Goku, who finally manages to surprise him.

Western Animation

 * Parodied in The Simpsons when a meteorologist tracking a hurricane informs Marge; "This is the worst storm I've ever seen. And I've seen three storms." Naturally, Marge is horrified.
 * In another Simpsons episode, Moe walks in a restaurant full of mafia goons and kingpins who all immediately turn their weapons on him. He remarks that's the "second most guns ever pointed at [him]."
 * Used in Avatar: The Last Airbender when Aang has his fortune read by Aunt Wu. Dumbfounded, she says, "I've never seen anything like this before! Your destiny--this is incredible--you will be involved in an epic battle that will determine the fate of the entire world!" Aang, not impressed, says, "Yeah, yeah; I know that already. But does it say anything about a girl?"
 * Lampshaded in an episode of the 2003 Teenage Mutant Ninja Turtles; when Donatello delivers this line, movie-savvy Michaelangelo says it along with him.
 * Regular Show: Skips is incredibly old and has seen just about everything...but for some reason he can only hazard a guess at how to deal with a problem so mundane as getting rid of skunk stink.

Real Life

 * Truth in Television: The words you do not want to hear at the doctor's office and why other doctors envy people whose last names were Turner, Klinefelter, Tourette, etc...
