Charlie Sheen: 'Bachelor' Father

The CBS sitcom "Two and a Half Men" is the No. 1 new comedy of the season, with an average of more than 15 million viewers a night.

Charlie Sheen stars as Charlie Harper, a fun-loving bachelor whose brother and nephew suddenly move in with him. And in a way, the show has been compared to a modern-day version of "The Odd Couple."

In light of the passing of Tony Randall, Sheen tells The Early Show co-anchor Rene Syler, "If we can achieve anything close to what those two geniuses pulled off, we would be lucky."

So far, ratings show the series has struck a chord with the audience. And Sheen could not be more pleased. "It's interesting because this year, the critical narrative to start the season was the death of sitcom, the death of the half hour, with 'Friends' and 'Frazier' going away," Sheen says. "We found an audience early on and they stayed with us and we're really grateful."

Not only is he having fun with the show, but he's also enjoying the family life it allows him to have.

"It's great because you get to shoot and every night go home to your family," he says. "Every month, get a week off. It's the closest thing to 9-to-5 in show business. I did films for a long time, traveling the world in so many locations and always being homesick. These days, I don't go through that."

The one thing he is enduring is the sleepless nights, thanks to his newborn daughter, Sam, with wife Denise Richards.

How much sleep he is getting? "It varies," he says, "Sometimes three hours, two." And yet he still manages to find the time to help others.

Explaining the breast cancer pin he was wearing, Sheen says, "A friend of mine years ago died from breast cancer. I had done this type of work, but usually behind the scenes with silent contribution and donation. And I just felt, like, when I was asked to be the spokesperson, that it was important, with all the women in my life, that it's important that we raise not just money, but overall awareness."
