After several days of back-to-back shocking interviews, Charlie Sheen was at his most bizarre on Tuesday night's edition of '20/20.' While many of the more stunning sound bites from the interview were teased prior to the telecast, it was still perplexing to see the actor continue his ranting and raving.

'20/20' journalist Andrea Canning and Sheen jumped right in, talking about his rampant drug use, his father Martin Sheen and his live-in girlfriends or "goddesses" as he lovingly calls them.

The 'Two and a Half Men' actor pegs the last time he took drugs to about a month ago when he "probably took more than anyone could survive." He claims he was "bangin' 7-gram rocks and finishing them because that's how I roll. I have one speed, one gear ... go!"

Sheen never let up: "I am on a drug, it's called 'Charlie Sheen.' It's not available cuz if you try it once you will die. Your face will melt off and children will weep over your exploded body," he said.

When asked how he'll respond to his children if and when they ask about his past, he replied, "I'm not gonna worry about it, or I can say, 'Hey, kids, your dad's a rock star...' They'll realize how cool Dad is!"

He doesn't seem worried about judgment from his kids -- just his own father. "I don't care whether he's my dad or the guy down the street or somebody that, like, fell out of the sky. No interest in that. I don't care if he's my dad. Back off with your judgment!" he exclaimed.
