Skateboarding star Jason Acuna, otherwise knows as "Wee Man," became a household name for appearing in MTV's highly popular Jackass television series and films. Born in Pisa, Italy on May 16, 1973, Jason is also the host of the skateboarding show of NESN. Acuna has achondroplasia, a form of genetic disorder that causes dwarfism. His short stature, however, did not hinder his skateboarding career in any way, and uses a shorter skateboard during competitions. Jack had a cameo appearance in the movie Grind, and had guest appearances in the TV show Wildboyz. He is also a playable character in skateboarding video games Tony Hawk's Underground 2 and Tony Hawk's Pro Skater 4.

In 2007, Acuna was featured in the CBS reality TV series Armed and Famous, together with five other celebrities such as Erik Estrada and Jack Osbourne. The show followed the celebrities as they train to become reserve police officers for the Muncie, Indiana police department. He also appeared on another MTV show Scarred Live. He has put out his own DVD called American Misfits.

Acuna is one of the contestants in the NBC reality show Celebrity Circus, which features six celebrities who will learn the ropes of circus life, including mastering death-defying stunts with high wires, flying trapezes, and fire dancing. The contestants will then face a panel of judges for critique. As Jackass is known to show and make fun of its stars fail stunts, Acuna says Celebrity Circus is very different. “It's black-and-white compared to what I'm used to,” he says. Nevertheless, he can’t decide which hurt more but he describes the experience as “painful” and “crazy.” In the end, though, he says he has gotten more flexible than he used to be.
