Mario Kart DS is probably the ideal lunch break distraction. We usually straight-up Versus mode until someone (me) breaks 100, or sometimes 200, or sometimes until we get to race on Tick Tock Clock. There's no better way to begin the digestive process.
Today didn't go quite as usual. When I broke 100, Proby broke it further. He explained that he'd been practicing all weekend, but the "why" does not concern me. I lost. Me! Mario Kart! Lost! Entropy is leaking into the universe, my friends.
