Here's a different approach...watching my son's JV game the other night. Officiating was sketchy, but it's a JV game. There is one of those clowns sitting at the other end doing the same thing as the guy in Mark's OP. During the second quarter, there is a time-out and the guy is reciting his litany of all the things the officials have missed so far. One of the refs calmly walks over, sits down beside the guy and has a quiet conversation with him. The guys laughs, pats the ref on the back, and never says another word the rest of the game.
Now I have no idea what the ref said to him, but they both ended up smiling and the problem was solved. Seems to me that that was a much better way to handle the situation than what was in the OP. But that's just my opinion, and while my opinion is not worth as much as Jurassic's, it's gotta at least be worth as much as that snaqwells guy!!
