How do you deal with horrible players?

I'm in a micro limits game clearing a bonus and I get Q/Q its 4 handed when someone raises 2$ a huge bet in .05/.10. I re raise all in, everyone folds to him, and he calls. He has A/5o. I am extremely happy that such a fish called me.

He flops quads. Lol. I mean sure he figured he had an over card, but he risked $16 on an over? Ugh.
