perosonally i like www.insultmonger.com i have used it and recomonded it. also the punch in the face doesnt hurt also. or do it my way and have an excesively large knife on your desk, in view of them as the walk in to your cubical. and then see if he says anything to ya. if he dose, pick it up and, for example, clean your nails, or something as long as it is in your hand.
