Jackass (2000)

You've heard it a million times before, but no, seriously: Do not try this at home! Life is one big double-dog-dare for the sophomoric superheroes of this low-brow cult hit, as they submit to a series of tasteless and often very painful stunts. It's relentlessly lowbrow, but some of these bits are so startling that you're bound to laugh, even if it's out of nervous shock.
