Release the anger and let your play speak for itself. Be the better man. There is nothing more satisfying then taking the high road, beating the p!ss out of someone and then shaking their hand at the end of the game without stooping to their level. They will probably be more irritated that they did not get a reaction out of you.
As far as beaning his son. Don't do it. Your beef is not with his son but with him. Plus imagine how you would feel if you hit him in the head or square on in the chest and put him in the hospital or even worse.
