“Jackass Number Two” is rated R (Under 17 requires accompanying parent or adult guardian). The Surrealists would have loved these guys, and relished the film’s signature image: the application of a leech to the surface of an eyeball. That, and the impulse to watch a 400-pound woman belly-flop on top of a midget. At the root of the “Jackass” project is an impulse to deny the superego and approach the universe, with all its hard edges and shark-infested waters, as an enormous, undifferentiated playpen.

You may prefer a Buster Keaton gag to the spectacle of a man leaping from a trampoline into a ceiling fan, but you can’t argue with its purity of expression. Debased, infantile and reckless in the extreme, this compendium of body bravado and malfunction makes for some of the most fearless, liberated and cathartic comedy in modern movies. Much of what follows is too obscene to be described here suffice to say that disreputable things are done with the ejaculate of a horse.

“Puppet Show” is the opening bit in “Jackass Number Two,” the second feature-length collection of stunts, pranks and self-inflicted trauma from Johnny Knoxville and his merry band of skate-punk yahoos. When Chris Pontius sheathes his penis in a cotton puppet, dangles it in front of a live snake, and then braces himself for the fangs while his buddies double over in glee, it’s known as “Jackass.” Prepare yourself for fits of uncontrollable laughter and waves of nausea as the guys launch their battered bodies into an onslaught of absurd situations. When the supermasochist Bob Flanagan nailed his penis to a piece of wood in front of a live audience, it was called performance art. Better than any sequel to a movie of a television show has a right to be, Jackass: Number Two dares you not to laugh.
