MMA Marketplace: T-shirt to shut up any mouthy friend

Let's say you're headed to the gym today, and you get assigned THAT guy as a sparring partner. The one who says he can submit anyone. The one who says "he trains UFC." The one who no one at your gym likes to work out with. What should you wear to knock him off his game a bit?

This. This shirt is $9.95 at Title Boxing and MMA, and would be a steal at twice the price. Obviously, it's not the shirt you should wear to your family's holiday party, but in the right context, this shirt is golden.
