Movie: Christmas Vacation
The scene where Clark W. Griswold sprays his non-stick invention on his saucer sled and then rockets down the slope, through traffic, etc. The first time I saw that in the theater I laughed so hard I thought I was going to blow out an eyeball!
Of course, the best part of that is a couple of scenes later when the sled is seen curbside with the rest of the trash.
I don’t know the name of the Laurel and Hardy comedy that had this one.
The two of them, dressed in tuxedos, are looking for the party they are supposed to attend. It is night and they come to a tall, white post that looks like a street sign. Stan starts toward it to climb up and read the sign at the top but Ollie, insisting that he will do it, stops him. So Stan gets down on all fours. Ollie uses him for a starter and laboriously climbs the post to read the sign which says “Wet Paint.”
Movie:Meet The Parents
Scene: Dinner at the parent’s house. The cork flying up and hitting the urn with the ashes, and the cat running over, “No Jinxie, No!”. Also, the cat milking conversation. I was laughing so hard I thought I was going to choke.
From The Money Pit starring Tom Hanks.
Walter Fielding gets stuck in a hole in the floor and hallucinates the Care Bears are there.
The bathtub falls through the floor, and Walter laughs uncontrollably.
When Walter gets tossed out of the window onto the scaffolding and unds up underneath the fountain peeing on his head.
When the steps fall apart while his girlfriend is running around screaming because a raccoon jumped on her.
Gotta love the Jesus.
Tale of Sir Lancelot. When they show the same clip of him running up the hill about 5 times only to have him suddenly slaughtering everyone in the castle put me in tears the first time I saw it.
I’m not sure about the details but the scene from The Boondock Saints where Connor, Murphy and Rocco get drunk at the kitchen table. Rocco gets too excited about the prospect of becoming a vigilante and slams his hand down hard on the table. Unfortunatly there are several guns on the table and one goes off, causing the quick demise of his junky girlfriends’ cat and a big red stain on the wall.
The next day Rocco’s girlfriend comes in and he tells her about the accident. They get into a fight and Rocco says that the cat didn’t mean anything to her anyway. He’s willing to support that claim by shooting himself through the head if she can think of the cats name on the spot. Well the girl start to brainstorm at a hilarious pace and shouts: MITSY! 
MP And the Life of Brian: The whole scene at the stoning…
“I don’t think it should be a crime, just saying Jehovah.”
“You’re just making it worse for yourself, you know!”
“Worse? How can it be any worse?” (starts kicking up dirt) “JEHOVAH! JEHOVAH JEHOVAH JEHOVAH!!”
The Bob Barker/Happy Gilmore fight scene…
Those are the first two that pop into my head. This is one of those things that I’ll think of 20 scenes as I’m driving home that have me cracking up every single time… but I just can’t think of any right now.
From one of the “Pink Panther” movies, I forget which:
Inspector Clouseau (Peter Sellers) is in the bathtub when he jumps out to answer the phone. His boss is calling, asking him to come down to the station. He gets dressed and leaves, leaving the bathtub running and the bathroom door closed.
About half an hour later, after a bunch of other stuff has happened and you’ve forgotten about this, he comes back home, opens the bathroom door, and is instantly knocked down by a massive wall of water rushing out. I’ve seen this movie twice, and I didn’t see that coming either time.

For some reason, the scene in Austin Powers where he’s driving the little electric cart down the hallway and has to do a five thousand point turn to turn around just cracks me up. Every single time. I’m laughing right now just thinking about it.
ok…
the Big Lebowski the WHOLE movie… just thinking about the movie makes me laugh…
" there’s a lot of ins, a lot of outs, a lot of what have you’s"
you have to love the dude!!!
The “Putting on the Ritz” stage set piece from Young Frankenstein
Also the “Tao rap” scene in A Chinese Ghost Story.
Inspector Clouseau goes to the Commisioner’s castle after the commissioner has gone mad. He pretends to be a dentist and they both get high on laughing gas. I don’t know if I can convay the mood that goes on. You just have to see it to laugh hard enough.
IMO, one of the funniest scenes comes from Trading Places.
The Duke brothers are just about to explain the rationale behind commodity exchange to Eddie Murphy’s character (Bill Ray Valentine). Before they begin, though, they do this whole really elementary break-down of the actual commodities they deal with. I mean, they go so far as to explain what bacon is used for, as if even a dummy wouldn’t know that you eat it for breakfast. They do the same for orange juice.
To convey how insulting to Billy Ray Valentine’s intelligence this condescending lecture is, Eddie Murphy does something brilliant and hilarious: He turns to the camera and makes eye-contact with the audience for like two seconds. The look says “what the fuck?” better than words could have had. And then he looks away and the dialogue resumes.
I know I probably did a bad job describing it, but it’s a scene that always makes me laugh out loud when I see it.
Yes, this is it, the one I was going to post. I really, actually, damn near pissed my pants in the theater when I first saw this. I came very close to having a wet seat. You forgot the part about the “wanted” poster.
OMG, how could I have forgotten that one.
The song “Uncle Fucker” from the South Park movie.
The scene in Jackass with the electrical stimulator. The guy puts one on each biceps. They turn it up, he starts screaming like a girl, everyone is laughing, and he can’t get them off of his arms because his arms are all convulsed because the biceps is totally in rictus.
The first scene with little Timmy and Roger Murdock (Kareem Abdul Jabbar) in Airplane! “I know you, you’re Kareem Abdul Jabbar. I like you but my father says you don’t work hard enough on defense.”
Also the Malkovich inside Malkovich scene from Being John Malkovitch.
The scene from The Blues Brothers, from before the concert (Elwood: This is glue. Strong stuff.) to Twiggy at the gas station to the chase (Its 108 miles to Chicago, we have a full tank of gas, half a pack of cigarettes, its dark, and we’re wearing sunglasses. Hit it.) to the last scene in jail playing “Jailhouse Rock.”
The hardest I remember laughing at a movie was at Ghostbusters - when they introduce the Sta-Puft Marshmallow Man
A Fish Called Wanda — Otto (Kevin Kline) is holding Archie (John Cleese) at gunpoint and makes him get a barrel of used oil. He then decides to get in a few insults before finishing him off, calling Archie pompous, arrogant, etc. Archie notices Ken (Michael Palin) slowly driving up in a steamroller and decides to distract Otto by talking in a mocking Texas accent and telling him how America lost the Vietnam War. This gets Otto’s dander up and he has to debate Archie to save face. Then the camera does a close-up of Archie’s face as he snarls “Yep, them Viet Cong boys kicked your asses REEEEEEAL good!!!”
The prologue to Raising Arizona, where H.I. is recounting how he met and married Ed and they tried to start a family. There’s a shot of them at a doctor’s office, and HI has a hangdog expression on his face as Ed’s crying her eyes out. His words: “But no. Her womb wuz as a barren field, from which mah seed could find no purchase.”
