Despite the fact that he contributes nothing beyond hyperbole, insults, and toilet references, he's often the most entertaining poster here by far. People like him can only bother you if you try to have an actual conversation, which we all know by now is utterly impossible. Responding to him (other than to make fun of him) is useless, because it's like walking up to a pile of crap and crapping on it - when you walk away, you still have a giant pile of crap, and you've only made it that much bigger.
He's only a net negative if you take anything he says as being the slightest bit serious.
