Even amidst recent concern from a CBS exec about Charlie Sheen’s behavior affecting the show and his career, Sheen still managed to raise eyebrows at a TV taping for Drew Carey’s new improv show.

According to the LA Times, his unexpected appearance on the program began with Sheen’s usual level of unpredictability:

At a taping of “Drew Carey’s Improv-a-ganza” at the MGM Grand Sunday night, cast members told the audience that they’d happened to meet Sheen on the Vegas strip earlier that day and invited him to join the show. Not known as one to refuse a good time, Sheen readily agreed, although when introduced during the show, he somehow managed to miss his cue. The cast was forced to improvise more than planned until Sheen appeared a few minutes later, looking unsteady on his feet.

In an improv game in which players took turns making up the lines of a story, Sheen’s first two contributions involved him referring to himself in the third person and suggesting, with colorful and unprintable language, that he was getting more than a little friendly with a “dead hooker.”

The evening’s performance with Sheen continued enough for him to offer up vulagarites referring to women.

While the actual dialogue of the evening was not confirmed by Sheen’s rep Stan Rosenfield, he did claim to believe Sheen’s appearance at the taping did occur.
