UFC Honcho to Sheen -- You Can Fight In My Octagon!
Charlie Sheen already has a venue if "Two and a Half Men" creator Chuck Lorre agrees to fight him in the octagon -- because UFC boss Dana White has invited them to be the "co-main event" at this weekend's big fight.
White tells TMZ, "BJ Penn is fighting Jon Fitch on Saturday ... [Charlie and Chuck] are more than welcome to be the co-main event."
In fact, Dana's even made a prediction -- saying, "I have Charlie Sheen by brutal knockout."
How can you bet against a guy with "fire-breathing fists?"
