Philadelphia fans are known to be a rowdy bunch, and Mr. G here is no exception. Thankfully he's more of the over-excited, goofy kind of rowdy as opposed to the "throw a broken bottle at the back of your head" type. This fan is so excited, he yells, screams, and even raps. He's like a more lovable Kanye.
Yes, if the Eagles even go to the Super Bowl he will explode.
