'Jackass' Guys Perform Painful Stunts on 'Tonight Show' (VIDEO)

As part of their 'Jackass 3D' promotional tour, the daredevil boys (sorry, we just can't bear to call them men) did some stunts in 'The Tonight Show' (weeknights, 11:35PM ET on NBC) studio. If they succeeded, audience members got prizes. First, Jason "Wee Man" Acuña strapped a raw egg to his forehead. If he was limber enough to high-kick and smash it (in three attempts), a fancy dinner was on the way for one attendee.

Next up, Steve-O endured some "free ball tee ball." In baseball cap and tighty-whiteys (no cup: "I'd be happy to prove that for ya"), Steve-O braced himself for "a severe hit" to his groin. If he could stay on his feet, another prize dinner.

Lastly, Bam Margera rode a skateboard down a ramp, holding a baby doll. A rope "clotheslined" him right at the neck. If, after crashing to the floor, he was still holding the doll, Papa John's pizza for everybody. Check the video to see how they fared.
