Rewarding someone for lying to you seems like a bad idea. Think about it. You're in a bar. You're trying to pick up a chick(or, in your case, a fat dude). You decide to be truthful so you say "Hey, My name is Tec. I'd like to take you home and nail you. I suck in bed, I'll probaby pee on your bathroom floor, make a snack before I sneak out and I definitely won't call you tomorrow." I don't think that will work.
Not if he expects to be rewarded for lying. And, since he voted for Coach, he probably does.
