The videos feature Bam Margera, Brandon DiCamillo, their friends, and Margera's relatives performing various stunts and pranks, interspersed with skate footage of Bam and other professional skateboarders. A trademark of the skating footage was to show unsuccessful trick attempts immediately followed by the same skater pulling the trick off. "CKY" started when Margera and his friends were in the same graphics arts class at school in West Chester, Pennsylvania. During class, they would go out to a field and film skits, eventually being compiled into the "CKY" series. In a 2002 interview, Margera said that more than 400,000 copies of the series have been sold.
