Surprise, surprise: Red Sox fans and Yankees fans don't like each other very much! Er, okay, so you already knew that. But the Red Sox fan in the video here went above and beyond over the weekend to show his disdain for the Evil Empire. He pounded about 40 beers (at least, it looks and sounds like he pounded about 40 beers) at Yankee Stadium during a Red Sox/Yankees game and then proceeded to get into a back-and-forth yelling match with some Yankees fans. And it was pretty damn entertaining.

Do you think he's still hungover?!
