Sometimes opposing fans come and they are just dicks (see - the Steelers) and sometimes they are hilarious. The Giants fans mostly fit into that hilarious category, watching the game, saying something funny, and generally taking the abuse that they were being pelted with in stride.
After the Giants scored this guy was cheering a bit and someone behind me said
Damn you and your glorious hair!
And then he let me take this photo of his, indeed, glorious hair.
