If Johnny Knoxville was the ringmaster of the "Jackass" (MTV, 2000-2002) crew, and Jason "Wee Man" Acuña its court jester, then Bam Margera was its matinee idol and its entrepreneur. An inveterate prankster as a teenager, Margera filmed his friends as they executed skateboard stunts and practical jokes, and later released them as part of a popular video series called "CKY." The videos helped to introduce Margera to Knoxville and the "Jackass" team, who made him their second-in-command for the eventual series and wildly popular feature films. Between "Jackass" projects, Margera became a one-man operation, producing his own prank reality series, "Viva La Bam" (MTV, 2003-05) and several follow-ups, as well as directing music videos and low-budget comedies and launching his own radio program and music label. Though his career was gangbusters, his personal life occasionally slipped into toxic areas through struggles with alcohol and public altercations. But his dogged determination to make a name for himself helped carry him past most of the trouble spots, and minted him as one of the most successful independent figures in the industry.
