Hard to believe, but Charlie Sheen has some regrets.
In particular, he told Jimmy Fallon on Monday night that he has second thoughts about his infamous catchphrase "winning," which went viral when he was ousted from his CBS sitcom for bashing the powers that be on the show and for general tabloid hijinks.
"What was I talking about, though?" Sheen asked during an appearance on "Late Night with Jimmy Fallon. "I'd lost my children, my job, my money, my stature and my mind. What was I winning?"
Sheen was appearing on the program to hawk his new FX show "Anger Management," admitting to the host that -- shock of shocks -- he's dabbled in a little rage control therapy himself.
It wasn't all self-reflection, though. The highpoint of the evening came when Sheen partnered with Fallon in a spoof video for "Clone Cologne." The faux commercial gave Fallon an opportunity to show off his furtive-eyed, chain-smoking Sheen impression with the former "Two and a Half Men" star on-hand as the real McCoy.
"Anger Management" premieres Thursday at 9 p.m. EDT.
