If you like your humor down and dirty--or just plain juvenile and scatological--then youll want to see CKY2K, which served in part as inspiration for MTVs Jackass. The title stands for "Camp Kill Yourself 2000," and ringleaders Bam Margera and Brandon DiCamillo prove theres nothing they wont do for a laugh, whether it means destroying a rental car, riding furniture tied behind moving vehicles, or performing Candid Camera-style practical jokes. For good measure, you get lots of footage of Bam and buddies doing skateboard tricks as well as their bizarre trip to Iceland (where, at one point, they heckle the house of rock star Bjork).
