I don't understand the fascination with Charlie Sheen. He is obviously an addict and he is out of control. As long as people are listening, Charlie will continue to rant and rave. He is a spoiled brat, that needs to hit rock bottom.
He's amusing. Remember when Brittany Spears shaved her head? People were all over that, but this is much more entertaining. Sheen is the Taj Mahal of ego, and people think that's funny. Enormous egotists, particularly ones who make really off-the-wall statements about themselves and sleep with former porn stars, are funny things.
