Charlie Sheen, TAH. Vintage 2011 Sheening:

"The run I was on made Sinatra, Flynn, Jagger, Richards, all of them just look like you know, droopy eyed armless children."

“I woke up and decided, you know, I’ve been kicked around. I’ve been criticized. I’ve been like the, ‘Ah, shucks’ guy with like this bitchin’ rockstar life. And I’m just finally going to completely embrace it, wrap both arms around it, and love it violently. And defend it violently through violent hatred.”

“I am on a drug. It’s called Charlie Sheen. It’s not available because if you try it once, you will die. Your face will melt off and your children will weep over your exploded body.”

“I got tiger blood, man. Dying’s for fools, dying’s for amateurs.”

“Women are not to be hit. They’re to be hugged and caressed.”
