Inside Charlie Sheen's shenanigans then and now

Charlie Sheen got fired from his job on "Two and a Half Men." He said it's OK. He didn't like the show. Sheen has been engaging in all kinds of unusual behavior for several months now. His life and career appear to be derailed. I was around for the first version of Sheen shenanigans back in the 1990's. We were scheduled to do an interview at 10 in the morning. Sheen locked himself in his dressing room for almost an hour. He came out not looking too good. And we muddled through a conversation. If memory serves, we didn't air it. Years passed and when his new show was about to debut on CBS we were set to talk again. He was on time. And the first thing he did was apologize for the way he acted at the previous interview. It was sincere. He seemed free of his demons then. But, not now.
