Tony Rock: Gary Coleman Out of Control?!

Gary Coleman loses it -- and it's all caught on tape! But before you rush to judgment, here's the back story on just what happened: It was all for a gag shot with a hidden camera for "The Tony Rock Project," airing Wednesdays on MyNetwork TV.

"It's the family business," says Rock, whose brother is none other than Chris Rock, about his new show. "The Johnsons have Q-Tips, the Firestones have tires -- the Rocks have jokes."

It all started out innocently with a fan asking the former "Diff'rent Strokes" star for an autograph and wanting to hang out. But unbeknownst to Gary, the fan is an actor -- and so is everyone else in the room. They prod him about his 1999 court case for hitting a female fan who was asking for an autograph, and then the fan with Gary starts to insist on pinching the star's cheeks! The tension starts to escalate, and Gary gets defensive, then into self-defense mode -- striking out at the fan with his phone receiver -- while trying to call the police.
