Some of Jim Carey's movies just broke me up the first few times...
There's Something About Mary.
Everyone laughs at THAT scene, you know the one!
Rat Race or Saving Silverman.
The Boondock Saints!!
MONTY PYTHON - THE LIFE OF BRIAN
Duplex, Meet the Parents, High Anxiety, Captain Ron, Two Can Play That Game.
Mouse hunt or the first episode of Home alone. If those do not make you rolf try The Party or Laurel and Hardy's Laughing twenties. If you could even check out The Great Race or like nice dialogue humor Faulty Towers is a treat.
Meet the Parents trilogy, The Hangover, Step Brothers, Wedding Crashers
The original "The Producers" with Zero Mostel and Gene Wilder.
Check out the British "Death at a Funeral"
Why is everything so green.
American pie and the sequels.
Its Mad Mad Mad World! how a comedy is generated when people run to aquire the buried treasure of a dead traveler. a beautiful presentation. i forget who has produced it but wonderful movie. Danny Kaye was an old master whose Inspector General was a master piece. i salute them.
"Kentucky Fried Movie" it's an oldie but goodie
I think it was called Rat Race. It had John Cleese, Rowan Atkinson, Whoopi Goldberg, can't remember all of them in it.
Tropic Thunder and Slither. These are the most quotable, one liner movies EVER.
