One year they should flash mob the Super Bowl. Don't tell anyone where it's at, and then have the players show up one at a time in a local park and paint stripes on it and play. They could bring the cameras, of course, but then it's up to the population of the city to find it and show up.
That'd be awesome.
Eliminate the racist "Chiefs" nickname and become the Kansas City Ermines. It's time, people.
