In the standup comedy world, Carlos Mencia has quite a reputation with his peers for stealing material (Joe Rogan famously called him out for it on stage at the Comedy Store in Los Angeles not too long ago). Until now however it's pretty much been petty theft ... can anyone even name a Joe Rogan routine? But now Mencia has graduated to stealing from the classics, which kind of pisses us off. Witness above, as Mensia appears to have lifted Bill Cosby's great "Hi, Mom" football routine almost word-for-word. Lousy bastard.

By the way, it's true, you know: No matter how many endless hours of catch you play with your kid, if he ever grows up to be a professional athlete, the first thing he's going to do when he gets his moment in the national spotlight is to give all credit to mom. That's just the way it is, and we wouldn't change it.

We bring this up, in part, because SI just pulled this on With Leather.
