It’s no secret that Charlie Sheen is gross and scary with a capital ‘S.’ And that the people who have shelled out $80 to see his disaster of a stage show, “Violent Torpedo of Truth,” have made a questionable decision. But I am truly baffled by the audience of more than 3,000 in Cleveland who, upon Charlie’s urging, began chanting “F**k that bitch!” with him in reference to his ex-wife, Denise Richards. Yes, Denise, as in the mother of two of his children. Denise, as in the one who, after his freak out in a hotel room with a prostitute in October, said, “We’re in an amazing place. We’ve been getting along great for the last year-and-a-half, and we’re doing our best. So as far as that situation, I’m just trying to protect the girls from it as much as possible.” And who just a few weeks ago told people not to judge him.
