Fat Mike and Chris spent an eternity arguing the Yankees' Billy Crystal stunt. While Mike essentially shrugged it off, Chris was vocally peeved by the whole thing. While people tried to argue that Russo would have no qualms getting on the court with Federer, and Willard pointed out he would likely jump at the chance to suit up for his beloved SF Giants, Chris was in full denial mode.
Let's just say the whole idea is "shaky" at best. Listen to the Doggy yelp.
