In its mission to shed light on bad behavior, truTV brings you 20 of the World's Dumbest Partiers. This installment features a tragically failed kegstand, some fantastic drunken dodgeball, an ill-advised cartwheel at a bonfire, and a convenience store customer staggering to the beer section for one last six-pack. With insightful commentary from Leif Garrett, Todd Bridges, and the rest of our hard-partying cast.
