New York crowds heckled Charlie Sheen during a stop of his "Torpedo of Truth" tour. He was met with boos and chants of "boring." Sheen had security on standby to throw out all hecklers. Did they throw out the whole audience, then? (LOL). 

Sheen, much like fellow mentally ill star, Britney Spears, really should not be out there. They need to be in treatment drug and psychological issues. Placing people with their mental state in a high pressure environment will lead to breakdowns and relapses.
