Normally mild-mannered Yankees manager Joe Girardi boiled over Wednesday night in Chicago. 

As Girardi was about to begin his postgame interview, the voice of a White Sox' fan echoed through the hallway beneath U.S. Cellular Field.

"Hey, Girardi, you bum! The Yankees suck!"

Because suddenly, there was Girardi breaking out of the pack, leaving a YES Network camera crew shooting his back, and shouting at a total stranger on his way out of the ballpark.

"Hey! Hey! Hey! Hey! Shut up! I'm doing an interview!" he said.
