Margera became famous for the hilarious and ridiculous stunts he and his nephew, Bam Margera, would pull on the show. Nicknamed "Don Vito," Margera was often the victim of some of the pranks planned by Bam and his co-stars, Johnny Knoxville, Steve-O, Chris Pontius and the late Ryan Dunn. Margera also made appearances in the Jackass movies and Viva La Bam.
Knoxville took to Twitter to remember his late friend and costar.
"RIP Don Vito," he wrote. "You will be missed.❤️❤️❤️"
ET previously reported that Dunn was the driver of the 2007 Porsche 911 GT3, which reportedly drove off the road and into the woods, where it crashed into a tree. The car was in flames when police arrived. There was another passenger in the vehicle with Dunn, and both passed away as a result of the injuries.
