What the world needs is a spin class at a gym that merges cycling with Mario Cart. You race against the other people in the class. You pick up boxes. You have to lean forward or push a handle bar to throw shells at people. You have to steer. Your resistance goes way up if you go in the mud. It'd be awesome. I would play every day. But until that's invented, I'm playing regular Mario Cart on the wii every day, sitting on my couch like a loser.
