Viewers are warned not to try the stunts at home, but that doesn't make up for the fact that these guys are poster boys for terrible behavior. They constantly fight with and taunt each other and make fun of others. Some of their pranks are designed to shock or alarm other people. The cast is virtually entirely male.
The guys' bodies undergo incessant abuse -- by bulls charging and tossing, snakes biting (producing blood), hammers and other objects slamming, riot-land mines firing, rockets exploding, falling, leaping, freezing, beating, kicking, sliding, colliding; crashing vehicles (shopping carts, skateboards); a gun is wielded to frighten a prank victim; crotches are hit or kicked repeatedly.
Frequent shots of naked bottoms, penises, scrotums, and pubic areas; a large naked woman drops onto Wee Man in an act of simulated sex (this is repeated with a large man later); "milking" of stallion to obtain sperm (which the guys then drink from a jar); images of objects and fluids put up rectums (beer and dildo); Spike Jonze appears in old-lady drag, with droopy bosoms visible (with the goal being to alarm passers-by).
Over 130 "f--s," as well as frequent use of other assorted other profanity ("hell," "s--t," "ass," etc.).
At this point, Jackass is its own brand name, with T-shirts, DVDs, and other products available.
Drinking, Drugs & Smoking
Smoking cigarettes, drinking beers. In one skit, Knoxville-as-Grandpa pretends to have his "grandson" both smoke and drink from a bottle (in a paper bag) in a public place, enraging onlookers.
