Charlie Sheen

In his heavily promoted 20/20 interview, Charlie Sheen said he has "a billion fans" and discussed his affinity for porn stars.

"You already know what you're getting before you meet them," he told ABC News's Andrea Canning when asked why he likes porn stars. Sheen also said he likes paying for prostitutes because "who wants to deal with all the small talk and the nonsense?"

Sheen denied being on any drugs and said to his knowledge there were no drugs in his house. "If I find them, I'll throw them away." Asked about the last time he took drugs, Sheen said, "I probably took more than anybody could survive. I was banging 7-gram rocks and finishing them because that's how I roll." Sheen also said he was proud of that moment "because I expose people to magic. I expose people to something they're otherwise not going to see in their normal lives."

Discussing his heavily publicized visit to the Plaza Hotel in October, Sheen denied choking porn star Capri Anderson and blamed the incident on the sleeping pill Ambien.

Sheen's twin boys with soon-to-be ex-wife Brooke Mueller were also shown on-camera during the special. Sheen said that "everything" makes him a good dad and that he's not worried about what kind of influence his actions will have over his five children. "They'll wake up one day and realize how cool dad is," he said.

Looking forward, Sheen reiterated he wanted to get Two and a Half Men back on the air. However, he dropped a threat to the show's production house Warner Bros. during his one of his workouts, or what he calls his "daily descent into death."

"I'm coming for you Warner Brothers. ... I'm a peaceful man with bad intentions."

Sheen said he was unsure if he and Men creator Chuck Lorre could ever work together again, and apologized again for the anti-Semitic remark against the writer-producer last week. He said he meant calling him "Chaim Levine" as a joke and denied being anti-Semitic. "Why would I be? That's a mindset that I would never entertain."

Sheen said his mission now is "just winning every day, defeat not an option."

Asked if he has ever been afraid of dying, Sheen asked "Who isn't? It's the greatest trip because they save it for last. It sucks that I have to do it, too." He also said his tombstone would read "something dotcom."
