Vincent "Don Vito" Margera, best known for his appearances on MTV's prank reality show, Jackass, died on Sunday, TMZ reports. He was 59.

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.❤️❤️❤️"

This is the second death that has occurred in the Jackass family. In June 2011, Ryan Dunn, who was also considered a fan favorite on the show, was killed in a car crash.

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.
