There are too many for just one thread:
Zombieland,
From Dusk til Dawn
Kentucky Fried movie (Particularly the 'Fistful of Yen' segment)
Down Periscope (Best fart scene on film, ever. The fart scene in Blazing Saddles, while classic, isn't even close)
Shaun of the Dead
Repo Man
Attack of the Killer Tomatoes (Somebody pass the ketchup!)
So I Married an Axe Murderer
Any of the Austin Powers movies except Goldmember
Pootie Tang
There's got to be more.
