Mitch Hedberg.

Wow, well he died. That really sucks. My roomate was going to see him tonight too. They say it was a heart attack but it was probably caused by a heroin overdose. I had recently saw him perform, for the first time, a few months ago with Steven Lynch and while he was quite funny, he seemed pretty messed up (though probably on alcohol). Upon reading other peoples comments about it, and from another friend who saw his show somewhere recently, he was messed up at every show he was at recently; sometimes too much. Quite sad, guess people thought it was an act.
