Dealing with the Antagonistic Table Coach

[MrStretchie]

Wondering if anybody has advice for dealing with a table coach that's basically a complete and utter assface.

Now.. I don't care if he berates my play (which he does all the time). The problem is that he absolutely TEARS APART the fish. He is a winning player, although far from optimal. But it's not so much that he takes their money, it's that he insults and berates them to NO END while doing it. He sits down at a table and within a couple of orbits the fish are either gone or tightened up considerably because they don't want to take his [censored].

I've tried rationally explaining to him (at a fishless table) why doing this is severely -EV. I've tried just suggesting that everybody block him since he's such a jerk. (This sometimes works with some fish..) I've tried ignoring, or making light of his comments. Even tried arguing with him on why their plays were justified. But really what I'd like to do is somehow get him to SHUT THE F UP.

Suggestions?
