He provides me with entertainment, I'll give him that much.
Partly because everything he does is pretty futile, since I could crush him easily. Second, because he's insulting people over the net (yay, way to go internet tough guy).
If he has the chance to read this, I say: At least get the balls to do it in person. Then, when you think you're all tough, I wonder if you'd find the fist firmly embedded in your face to be a decent argument against your claims?
