* "I'll bet you twenty bucks I can get you gambling before the end of the day!"
** Even better in that he doesn't realize he's already won.
* Lloyd's [[LaxativePrank revenge]] on Harry.
* "His head fell off?!"
** Even funnier is Harry's follow-up, "Yeah, he was pretty old..."
-->'''Lloyd:''' That's it. I've ''had it'' with this dump! We got no food, we got no jobs, our pet's '''HEADS ARE FALLING OFF!!'''
* When Lloyd accidentally goes the wrong way during the road trip:
-->'''Harry:''' Huh. I expected the Rocky Mountains to be a little rockier than this.
-->'''Lloyd:''' I was thinking the same thing. That John Denver's full of shit, man.
* When Lloyd pulls up next to Harry on a Vespa, and explains that he sold the Shaggin' Wagon for it and gas money.
-->'''Harry:''' Where did you find that?!
-->'''Lloyd:''' Some kid back in town. Traded the van for it straight up. I can get 70 miles to the gallon on this hog.
-->'''Harry:''' [{{Beat}}] [[IHaveJustOneThingToSay You know, Lloyd, just when I think you couldn't possibly be any dumber,]] [[TranquilFury you go and do something like this]]... ''[[BaitAndSwitchComment and totally redeem yourself!]]''
* "It's okay! I'm a limo driver!"
* "We landed on the moon!" [[ThrowItIn Ad-libbed]] by Jim Carrey, to boot.
* Harry introduces himself to Mary by saying "Nice set of hooters you got there" completely out of the blue. Although he makes a quick save by claiming that he's referring to the snow owls.
* The snowball fight between Harry and Mary. After Mary playfully tosses some snow at Harry, he retaliates by [[DisproportionateRetribution pegging her in the face with a snowball at point-blank range as hard as he can]]. It only escalates from there.
* Lloyd's dream sequence, which involves the GroinAttack to end all Groin Attacks, ripping a guy's heart out, a kiss from hell, and ends with Lloyd nearly hitting a semi head-on.
* Harry and Lloyd replacing the ransom money with I.O.U.s. Watching how they spend it is funny enough, but then [[ChekhovsGag the Big Bad finally opens the briefcase at the end]] and nearly blows a gasket.
-->''"Go ahead and add it up. Every cent's accounted for. Look, see this? That's a car. 275 thou. Might wanna hang onto that one."''
* When Harry explains that he survived getting shot because the FBI gave him a bulletproof vest.
-->'''Lloyd:''' ...[[FridgeLogic what if he shot you in the face?]]
-->''(beat)''
-->'''Harry:''' ''(to FBI)'' [[DumbassHasAPoint What if he shot me in the face?]]
-->'''FBI:''' [[TheNeedsOfTheMany That was a risk we were willing to take.]]
* The look on Harry's face when Lloyd has his hand in his coat [[spoiler:(ready to pull his gun during his ImagineSpot)]].
* Lloyd outwits Sea Bass at the diner by somehow getting him to put their lunch on his tab.
-->'''Harry:''' That was genius, Lloyd, sheer genius. I mean, where did you come up with a scam like that?
-->'''Lloyd:''' Saw it in a movie once.
-->'''Harry:''' That's incredible! So what happened, so the guy tricks some sucker into picking up his tab and gets away with it scot-free?
-->'''Lloyd:''' No! In the movie, they catch up to him a half-mile down the road and slit his throat. ''(giggles)'' It was a good one!
-->'''Harry:''' ''([[OhCrap suddenly driving a]]'' [[OhCrap lot]] ''[[OhCrap faster]])''
* When Lloyd first suggests to Harry that they go to Aspen.
-->'''Lloyd:''' What are we doing here, Harry? We've gotta get out of this town!
-->'''Harry:''' Yeah, and go where? Where do you wanna go?
-->'''Lloyd:''' I'll tell you where: someplace warm. Where the beer flows like wine. Where beautiful women instinctively flock like the salmon of Capistrano. I'm talking about a little place called ''(whispers) Assspeeen''.
-->'''Harry:''' I don't know, Lloyd; the French are assholes.
* Extra gloves.
** ''EEEAAAAAHHHH!'' HARRY! YOUR HANDS ARE FREEZING!
* Also the PottyHumor where Harry just lets go and pees during the ride... the pair are frozen together by the time Lloyd stops.
* "Dear Gas Man, packed up and drove to Aspin. Sorry about the $. Lloyd and Harry." *smiley face*
** Even funnier since [[MistakenForBadass the villains think that Harry and Lloyd are criminal geniuses playing them for fools]], taking "Gas Man" to be a reference to Mental's ulcer problems.
* "Hey...you wanna hear the most annoying sound in the world?" Doubly funny if you watch Jeff Daniels [[{{Corpsing}} start to lose his shit]] before the camera cuts to Mike Starr, also trying not to laugh.
* At the bar while Lloyd is waiting for his supposed date with Mary, Beth shows up and starts [[MotorMouth rambling]] about her [[spoiler:non-existent]] ex-boyfriend:
-->'''Beth''': And I said: "Run, Beth, run for your life before this man kills you both." Then do you know what the klutz did?
-->'''Lloyd''': ''(in HeadDesk)''...No, and I don't...'''''CAAAARE...''''' ''(back to HeadDesk)''
* Lloyd's attempt at a LoveConfession is fantastically stupid. This line is just the tip of the iceberg: ''"What do you think the chances are of a guy like you and a girl like me..."''
** And then when Mary tries to tell him it's "more like one out of a million":
-->'''Lloyd:''' [[CompletelyMissingThePoint So you're telling me there's a chance?]] [{{Beat}}] '''YYYYYYYEAH!!!'''
** Lloyd practicing a big romantic speech, ultimately screwing it up in, of course, the most hilarious way he could.
-->'''Lloyd:''' I desperately wanna make love to a schoolboy.
* The final scene in the movie was originally supposed to [[spoiler: have Harry's line be the same, then Lloyd would actually get them on the bus with the bikini models]]. The finished ending is the result of JimCarrey looking at the scene and going "Well yeah, but wouldn't ''this'' [[RuleOfFunny be even funnier]]?"
* The trailer for the movie, especially this line: "If they each had half a brain, they'd still only have half a brain."
* "''MOVE IT OR LOSE IT, SISTER!''"
* Doubles with an inversion of FridgeBrilliance: Harry and Lloyd pick up Mental as a hitch-hiker, despite the fact that they SAW him at their apartment, with a gun, merely days before. Neither even thought to mention "hey, doesn't this guy look a lot like the gas man?"
