Everything from the "Don't Let The Balloon Touch The Floor" to the useful and exciting "who can run the fastest to the fridge and back before the tv show comes back on."

Or maybe the IOC would consider adding some of these weird sports to the next Olympics. We'd pay good money to watch horse vaulting.
