It looks like the Gang of Oscar is stifling art once again. Poor Robin Williams. He had a little bit all prepared and they went and told him he couldn't do it.
Bet they would have let him do it if it was funny.
Celebrities receive so much reinforcement that they start believing pretty much anything they are doing is funny, entertaining, or interesting, just because they are the ones doing it. When that happens, we are only a few years away from that bittersweet moment when we hear a nostalgically familiar voice doing voiceovers for bank and insurance commercials.
Good luck with that new career there, Mr. Williams.
