Mandel `afraid' after Chappelle attack

Howie Mandel says he's “afraid” after an audience member with a knife blade tackled Dave Chappelle onstage this week.

“Watching what happened to Dave last night confirmed my fear,” Mandel told Extra.

“I was watching it kind of live on Twitter and I turned to my wife and I said, `I don't want to. I don't want to go on stage. I'm just really afraid.' ”
