Bill Cosby is going to beat the pudding out of Carlos Mencia. Long the subject of joke-theft accusations, Mencia, apparently, thinks it's not stealing if the joke is over 20 years old. A new Web video begins with a scene from Bill Cosby's 1983 show, "Himself," in which Cosby jokes about a father teaching his son to play football. Cut to Mencia's "No Strings Attached" from March 2006, and he's delivering the same joke—ending and all.
