Ok, this is REALLY simple. First, ask him to prove that you signed this contract. If he can't, you're in the clear, AND he looks like a doucebag. If he CAN, then you put in your two weeks notice, and THEN stop showing up to work. What's he gonna do, fire you?
This question is so simple, I'm not entirely convinced you aren't just trolling.
