For me it's important to try to find humor in suicide and the emotions, pain that come with it. Or then all the suffering was just that.
Doug Stanhope has the best suicide bits, Carlin's not bad. I think Louis CK was average couldn't tell whether he was sincere. I just don't find myself allowing myself to be amused by this because Seinfeld is completely insensitive to the matter, if he ever found himself in suicidal distress and saw this bit, he'd be a whimpering mess curled up in a corner acting like he's Billy big bollocks here.
