Dumb and Dumber

Dumb and Dumber is a 1994 film starring Jeff Daniels and Jim Carrey, directed by the Farrelly Brothers. Lloyd Christmas is a friendly, though somewhat sadistic and more than somewhat dimwitted, limo driver who lives with his Heterosexual Life Partner, Harry, in their Rhode Island apartment. Lloyd's life is turned around when he falls in love with Mary Swanson (Lauren Holly), a rich female client who leaves her suitcase at the airport. Lloyd talks Harry into going on a road trip to Colorado to return it.

In 2012, it was announced a sequel will be filmed with Jim Carrey and Jeff Daniels returning along with the original directors.

 * Anticipatory Breath Spray: Except he misses his mouth entirely
 * Animated Adaptation: The Hanna-Barbera-produced Dumb and Dumber cartoon in 1995, which featured a female beaver named Kitty as the Straight Animal to Lloyd and Harry.
 * A female beaver named Kitty. Now there's a Parental Bonus.
 * Attempted Rape: Sea Bass attempts it on Lloyd.
 * Beat Still My Heart / And Show It to You: During his dream sequence, Lloyd rips the Kung-fu Chef's heart out of his chest and shows it to him (before putting it in a doggy bag and giving it back).
 * Big Damn Heroes: Harry has two of these moments: in the gas station bathroom where he foils Sea Bass' Attempted Rape of Lloyd and again in the hotel near the end.
 * Although the first was unintentional.
 * Book Ends: Lloyd grabbing Harry by the head and saying "Do you realize what you've done?!"
 * Briefcase Full of Money: It drives the plot.
 * Brick Joke: The woman that Harry offends at the gas station shows up later in the film.
 * The blind kid Lloyd sold the dead bird to appeared in tears in a news report on TV much later in the film.

"Lloyd: I want to ask you a question... straight out, flat out... and I want you to give me an honest answer. What do you think the chances of a guy like you and a girl like me... ending up together?
 * In one of the alternate endings, the blind kid-dead parakeet joke would have been taken even further:
 * Butt Monkey: Oh so many. Mental, Sea Bass, the blind kid, and Harry and Lloyd themselves.
 * Check Please
 * Chekhov's Gunman: See Brick Joke.
 * Comically Missing the Point: So many times.
 * "You mean, not good like... one out of a hundred?" "I'd say more like one out of a million." "...so you're telling me there's a chance!" "Husband!? Wait a minute... what's all that one-in-a-million talk?"
 * Cool Car: The Shaggin' Wagon. They even have it back in the cartoon.
 * Corpsing: During the "Most Annoying Sound" scene (which was ad-libbed by Jim Carrey), it's obvious that the actor who plays Mental is trying very hard not to laugh.
 * Diabolus Ex Machina:
 * Diner Brawl: Averted. Sea Bass just spits in Harry's burger, and then gets conned.
 * The Ditz: Lloyd and Harry personify this trope.
 * Downer Ending: Subverted.
 * They had planned on shooting an alternate ending, but Jim Carrey disagreed.
 * Drowning My Sorrows: Lloyd does this when he believes that Mary stood him up.

 * Evil Laugh: Lloyd's sadistic laugh after exacting revenge on Harry.
 * Exactly What It Says On the Tin: Some people have found that, rather than being funny, the movie is just... dumb.
 * Extreme Doormat: Harry. Throughout the movie, he comes off as a little smarter and more sensible than Lloyd but for the most part goes along with everything Lloyd does partly because he's just very passive.
 * Fan Service: Mary during Lloyd's dream sequence.
 * Greasy Spoon
 * Groin Attack: Lloyd's dream sequence includes an extremely exaggerated one.
 * Heterosexual Life Partners
 * Hey, It's That Girl!: Mary's stepmom is Inga.
 * Hilarity Ensues
 * Hoist By His Own Petard:
 * I Drank What?: The scene where a cop pulls Lloyd and Harry over. He asks for them to give him their "beer", which is actually Lloyd's urine. He drinks it, much to his displeasure after doing so.
 * Imagine Spot: Lloyd has two: one while driving, which causes him to almost crash, and one at the end in a faux-Twist Ending, wherein he.
 * Imperial Stormtrooper Marksmanship Academy: "Harry! You're alive! And you're a horrible shot!"
 * Incredibly Lame Pun: "Life's a fragile thing, Harry. One minute you're chewing on a burger, the next minute you're dead meat."
 * Indulgent Fantasy Segue: Near the end when Lloyd
 * I Like Those Odds. Qualifies as sort of a Crowning Moment of Heartwarming.

Mary: Well Lloyd... that's difficult to say... you really don't...

Lloyd: Hit me! Just give it to me straight! I came a long way just to see you Mary. The least you can do is level with me. What are my chances?

Mary: Not good.

Lloyd: (gulping) You mean, not good like one out of a hundred?

Mary: I'd say more like... one out of a million.

Lloyd: (Beat, then grins happily) So you're telling me there's a chance."

"Harry: Freda and I had such a wonderful time. But right after the blue, she send me a John Dear letter.
 * Jerkass: Both are stone stupid, but while Harry is well meaning and even kind in his own bumbling way, Lloyd comes off as rather sadistic and highly mean-spirited, and not always obliviously.
 * Laxative Prank: Lloyd does it to Harry as revenge, since he supposedly stole Mary from him.
 * Malaproper: "I have a rapist's wit."
 * Most Annoying Sound: The hitchhiker scene. The Trope Namer.
 * The Nineties
 * Obfuscating Stupidity: The hitmen think Harry and Lloyd are doing this - the guy thinks a letter to the gas man is to him because of his stomach problems, and so on.
 * Oh Crap: Two instances, both with the same musical chord. The first is when Lloyd is in a gas station bathroom, looks at some graffiti left by and realizes he's right on time for "manly love". The second is when Harry suffers the effects of Lloyd's Laxative Prank and discovers that the toilet is broken.
 * How about the look on Lloyd's face when
 * Perverse Sexual Lust
 * A Plague On Both Your Houses: The duo accidentally poisons a hitman chasing them, and he dies screaming "You... son of a bitch!" And Harry gets sad.
 * Pop Star Composer: Todd Rundgren.

 * Double Standard Rape Male On Male
 * Rule of Funny: The whole film.
 * Road Movie
 * Sexual Karma: Averted.
 * Shout Out: The protagonists Harry and Lloyd are named after silent film star Harold Lloyd.
 * Stalker With a Crush: Lloyd to Mary.
 * Stealth Pun: Lloyd's last name is Christmas. If he and Mary got married, her name would be Mary Christmas. The unrated version explains the joke.
 * Toilet Humor: So many times it borders on Refuge in Vulgarity, one of which actually involves a (broken) toilet.
 * Tongue On the Flagpole: "Oh, look, frost."
 * Trailer Spoof: The trailer for Dumb and Dumberer disguised itself as a trailer for The Hobbit, leaving every member of the audience sorely pissed.
 * Written in Infirmity: Jim Carrey chipped one of his teeth prior to production and wore a cap on it to cover it up. However, he removed it when playing Lloyd because he thought it made his character look more deranged.
 * He actually chipped it before he even became an actor, and just wore a cap for every role but this one.
 * You Answered Your Own Question:

Lloyd: Did she give you any reason?

Harry: Yeah I called her up. She gave a bunch of crap about not me listening to her or something... I don't know I wasn't paying attention."
