Buddy is a huge fish but he doesn't know it. What's my line?

[apefish]

This question has always baffled me. I really don't know the right play here.
He talks trash at his tables and any competent player pegs him as a fish within a few hands against him.
He doesn't care about learning how to play as much as he just wants to play big pots and gamble.
Short of giving you all his screen name (which I won't right now because he's a buddy first still) what the hell do I do?
His game has massive holes and he has no bankroll management.

Stop caring?
Hookers and blow?
