Borrow some Nos fittiments and the bottle from a friend, install it, and raise the ante to $50, best 2 of 3 runs. That way he can watch you burn him, toy with him, and burn him again.

But assuming you don't have the richest and dumbest friends, I'd say that he probably doesn't have much on you, so just go with the weight reduction. It's free (read SCC this month, although I'm still disappointed in the article for some strange reason).

Good luck.
