Aren't you glad you're not a FILL IN THE BLANK fan? We all know your favorite pro football team is by far superior. Rivalries (like the Eagles and the Ravens, the Cowboys and the Redskins, the Patriots and the Jets) make the game that much more exhilarating. Don't just talk smack - wear it and make your rivalries cry.
Take the Most Interesting Man's advice, and proudly show off your hatred for those Niners! I don't often hate, but when I do...I prefer to hate the San Francisco Forty-Niners! Stay victorious, my friends.
