From the official site:
Nicknamed "Fat Boy Phil", Phil was thrust into stardom as target of his prankster son Bam, on MTV's Jackass and Viva La Bam. He has been involved in numerous stunts between the two shows, his favorite being when Bam woke him up in the middle of the night with firecrackers. A native of Pennsylvania, Phil has used his notoriety from reality shows to his advantage parlaying it into a movie career. He starred as "Fat guy with Watermelon" in Haggard in 2002, as well as the sequel in 2003.
Previously an employee of Acme supermarkets, Phil's current regular job is "paperwork". Phil has been married to his wife April, since 1976. They have two sons, Bam and Jesse.
