Sheen tries to trademark 'Duh, winning'

LOS ANGELES, April 5 (UPI) -- Charlie Sheen's publicist says the Hollywood actor intends to trademark 22 of his popular catchphrases such as "Duh, winning" and "Vatican assassin."

Larry Solters, Sheen's representative, told EW.com Tuesday Sheen is also looking to secure the rights to "Tiger Blood," "Rock Star From Mars," "I'm Not Bi-Polar, I'm Bi-Winning" and more than a dozen other gems he has made famous during his recent media blitz.

Sheen has been making headlines in recent months for his battle with substance abuse and related erratic behavior.

Prior to and after being fired from TV's "Two and a Half Men," he gave numerous interviews, during which he slammed his employers and made outrageous claims about his own talent and importance.

He is now touring in a one-man stage show called "My Violent Torpedo of Truth: Defeat is Not an Option," which has received largely negative reviews.
