Charlie Sheen what can you say?  It seems he's gone off the deep end, but according to him he's just Charlie.  Is it drugs?  He's said interview he says he did more drugs that anyone could survive.  Is he strung out? Has he gone crazy?  You be the judge.

Either this is genius entertainment and acting or Charlie is beyond help.  Don't be surprised to hear people using Sheen as a verb.  "Wow, man that guys is sheening."
