You get dealt a pocket pair between every 16 and 17 hands, and against a maniac you have the whole table working against one player.

I generally sit this one out and only call with extremely large hands to his crazy all-ins. I consider myself a solid player and I don't want to reduce my equity edge to a AK vs J9 64/36 type of situation. You're ahead, but 36% chance to win a hand is large enough to make you see red when they hit their cards and you don't. I'd rather profit off people's mistakes where they have 0-20% chance to win the hand.
