TMZ said he did not know, I still have a hard time believing this isn't staged somehow. I mean, until the Oscars come out and ban him or do something its incredibly suspect to me. If this was for real, it was an assault on live TV and for nobody to do anything about it just is crazy to me. Maybe everyone is still in shock over this, I don't know.
Also want to add, holy shit learn how to take a joke. There is nothing worse than people who get offended by a comedian. I was at an Anthony Jeselnik show at a comedy club one time and there was a guy who stood up in the middle of the show and caused a scene because he was offended by a joke. Comedians make jokes, that's what they do.
