Yankee fans are trying to organize a Moon Big Papi event during his last game at Yankee Stadium. Long story short, and it's detailed on their website, during Ortiz's first at bat in the game on September 29th, everyone is to moon David.
As a Red Sox fan, I find this act completely ridiculous hilarious. The commentators on TV wouldn't know what to do. The TV cameras would have to scramble to show something else, hopefully zooming in directly on Ortiz's face leaving no room around the edges for a rogue rump.
I hope they do this because I think David wouldn't find it very funny.
