Mitch Hedberg
reported dead, still
performing through the tenth despite his own website linking to
another report of his death.
All of the other sources (Comedy Central, MTV News, et cetera) quote Mitch's hometown papers -- either the Star Tribune or the Pioneer Press. No other legitimate news sources have the information on their own merit. And besides: If Howard Stern has the news first, there's a problem.
He's a hell of a comedian, but Mitch? Leave the April Fool's Faking Your Own Death bit to Andy Kaufman.
