**** (out of five)

There aren’t many entertainments that can be recommended specifically because they’ll make you laugh until you gag, but then that’s the power — and the glory — of Jackass.

At its finest, Jackass Number Two — much like the earlier Jackass The Movie, and like the MTV series which started it all — is the most effective physics lesson you will ever see: “If you do this, this will happen. So you really, really shouldn’t do this.”

There’s really no way to describe the Jackass experience to someone who doesn’t already know what it is ... at least, not without sounding just as insane as any of ringmaster Johnny Knoxville’s team of cheerful daredevil idiots, who repeatedly rush headlong into dangerous situations in order to laugh about them afterward — once the bleeding stops.

When they’re not rigging up elaborate ways of shocking each other, or luring one another into taking a punch to the face, they’re lining up to play teeter-totter games in the presence of an angry bull, or bungee-jump off a very high bridge while attached to another person, or serve as test subjects for an anti-personnel device that repels mobs by firing hundreds of little rubber balls at high speed at their chests.

Knoxville’s buddies have names like Steve-O, Bam, Wee Man and Spike Jonze. (Jonze is probably better known as a movie director, but evidently his real passion is walking around disguised as an ancient woman with a habit of falling pendulously out of her clothes.)

Wanna see someone walk blindfolded into the path of a charging yak? Wanna see someone go fishing for sharks with live human bait? Wanna see Mark Zupan, the rock star of quad rugby, go flying over a lake in a rocket-propelled wheelchair? All you have to do is buy a ticket.

And try to see it on an empty stomach.
