June 27, 2012 -- intro: Charlie Sheen is a man who speaks his mind, makes no excuses and gives few apologies.
In a recent interview with "Nightline," the 46-year-old actor, who became famous for bad-mouthing almost everyone in his wake, talked about his checkered past with blatant honesty.
"I don't walk around with a ton of guilt," he said. "I don't walk around with a ton of shame. I don't think it really serves in any way, you know, makes anything better."
But what a difference a year makes. Last year, Sheen was a crazed actor whose public meltdown included wild parties, a horde of women he called "goddesses" and his bizarre "winning" catchphrase, all contributing to his being fired from the sitcom, "Two and a Half Men."
Now, a more subdued Sheen is starring in a new show, "Anger Management," a title not void of irony. The actor said he is different from the man he was last year, with more "sanity" and "integrity."
"There was such a laundry list of so many elements and all the components of what led to that whole train wreck, that whole wipeout, whatever you want to call it, that violent torpedo that flew out of my mouth," he said.
But there are still a few eccentric quirks to Charlie Sheen's persona. The actor said he wears blue underwear each day and buys 4,000 lottery tickets a week, despite being a multi-millionaire.
"[Money] can't buy you happiness, but it can give you choices in certain areas that can ultimately lead to a happier time or happier self," he said.
Here are some other interesting facts you might not have known about Charlie Sheen.

They will even travel together so their daughters can be with both parents.
"Denise is terrific," Sheen said. "She been a great friend and a great confidante and a great mom to those girls... and I think that if we're not friends and [the girls are] suffering, then shame on both of us."
As for getting married again, Sheen didn't seem too keen on the idea.
"I don't want to wear the golden sombrero of marriage, Sheen said. "I think that if I can find the right person that is OK with not having a document to say that yeah, we really love each other, that would be OK."

His wild rants, including videos he posted of himself online last year, have earned him over 7.5 million Twitter followers, more than Khloe or Kourtney Kardashian, which surprised Sheen.
"I still own the whole experience," he said. "Good, bad or indifferent, win, lose or draw, that's-- there were some moments to have lived inside that no one could ever take away from me. And that's pretty cool beans."

Over the years, the actor has starred in other popular films including, "Ferris Bueller's Day Off," "Platoon," "Wall Street" and "The Rookie." He even played himself in the 1999 dark comedy, "Being John Malkovich."
"There's a respect level for the longevity that I've had," Sheen said. "I'm in my 30th year, which I'm kind of proud of and I'm still here to tell the stories."
After breaking into television in 2000 on the TV series, "Spin City," Sheen landed his first major TV role on "Two and a Half Men" in 2003. He became the highest-paid actor on television, but his bad boy behavior led him to be dismissed from the show last year.
"But I think that it's not just about being responsible, or about the antics. It's also about continuing to hopefully do good work and deliver myself in projects that people can still root for," Sheen said.

CBS canceled the rest of the show's fourth season the following month after Sheen publicly attacked series creator Chuck Lorre. Warner Bros. Television went as far as to ban Sheen from its studio lot. Sheen was officially dismissed from the show in March 2011 and replaced by actor Ashton Kutcher.
In the rocky aftermath, Sheen continued to bash Lorre and filed a wrongful termination suit against him and Warner Bros. The actor was awarded $25 million in the settlement last September.
But as part of his "I'm turning over a new leaf" persona, the new Sheen seemed to want to put the mess behind him. If he were to see Lorre today, Sheen said he would greet him warmly.
"I'd give him a hug and say, 'sorry bro, I was way out to line. I still don't agree with how you handled things. But let's at least-- not be enemies,'" Sheen said. "I would definitely want to just show some respect."

While he was the highest-paid actor on television when he starred on "Two and a Half Men," Sheen stands to make up to $200 million with "Anger Management."
