Let's Handle This Like Adults T-Shirt
Let's face it, even as adults, we fight. We probably argue more as adults than we did as kids and about things that are just as stupid, if not more (you know, politics, religion, where to eat, whose sports team is better).
That's why this T-shirt is the reminder of the ultimate decision maker and argument solver.
Good old rock, paper scissors, man. Nothing beats it. Let's go, best 2 out of 3 wins.
