Wrigley Field "Bleacher Bums" Cheer On...A Rat?

Maybe it was a slow part of the game. The Chicago Cubs had a home game recently, and you could hear lots of cheers coming from the bleachers. Obviously the home fans rooting on their Cubbies, right? Guess again. It all had to do with a RAT, who was trying to make a successful jump near the bleachers. His jump came up short a few times...would the rat finally prevail?
