From Wikipedia: Viva La Bam is an American reality television series that stars Bam Margera and his friends and family. The show is a spin-off from MTV's Jackass, in which Margera and most of the main cast appeared. Each episode had a specific theme, mission, or challenge which was accomplished by performing pranks, skateboarding, and enlisting the help of friends, relatives, and/or experts. Although partly improvised, the show was supported by a greater degree of planning and organization.
