TV moments that made me fall out of the chair, laughing: the finale of Newhart, when Dick/Bob wakes up next to Emily; the power walk in "Smile Time"; the GWTW Carol Burnett skit.

Movies that did the same: Airplane! (just about any scene, but on my first viewing at the age of 14, the one that sent me into hysterics was the automatic pilot getting a blow job from Elaine); Blazing Saddles (especially "I'm Tired"); and Who Framed Roger Rabbit ("My Uncle Thumper had trouble with his probate, and he had to take these biiiig pills..." "Not prostate, you idiot--probate!").

hat dialogue between Woody Allen and Diane Keaton in Love and Death that manages to reference every major work of Russian fiction in about 20 seconds

"Excuse me, will you hold my bosoms while I adjust my belt?"

"Uncle Fucka" during the South Park movie.

My brother and I should never have been allowed to see that movie together. We laughed so hard through the whole thing that I think we made people get up and move away from us. Particularly the "Les Miserables" montage in the middle-end.

In terms of recency, the scene in Wedding Crashers where Vince Vaughn's character is getting the hand job at the dinner table had me so distracted with laughter that I was glad the filmmakers didn't expect us to pay attention to anything else. At least, I'm hoping they didn't.

Nick's song "Lady L"

That was hysterical.

His Girl Friday and The Awful Truth are the classic movies that I find funniest. That scene in The Awful Truth when Cary Grant and the music instructor are beating each other up off-screen and Irene Dunne is trying to pretend that nothing is going on -- comedy gold.

And I think the episode of The Office (UK version) where they have the training seminar is about as funny as 30 minutes can be. I often think about the "postage stamps as legal tender" bit.

"You know, because...dogs."

I even have the song on my iPod. But I think the funniest Office bit is still the midget/dwarf/elf conversation.

"Uncle Fucka" was freakin' awesome.

His Girl Friday and The Awful Truth

Oh yeah. I love those movies.

I can be brought to a helpless state by a good use of (ring ring) "Cock."

Oh! Pretty much any part (or ALL) of Dirty Rotten Scoundrels will reduce me to helpless, howling laughter.

Much of the first few seasons of Coupling, but especially Lesbian Spank Inferno, and the one with the Israeli chick. I know one day at krav the word shadayim is going to slip from my lips unwarranted.

But I think the funniest Office bit is still the midget/dwarf/elf conversation.

Just David Brent's hand gestures alone in that scene crack me up.

I know I'm in the minority on this one, but Christian Bale's little speech in American Psycho about the deep meaning behind Huey Lewis & the News' music, and the little quick dance he does to "Hip to Be Square" leaves me cackling every single time.
