A number of years ago the Dolfelon fans had shirts that said 'Buffalo Sucks'. Vendors would sell these shirts outside of the stadium.
Well, one Sunday, I went to the game with a bus full of Fort Lauderdale police that happened to be Bills fans. We told the bus driver to pull over by the vendor. The vendor came over thinking he was about to make a fortune. When he got a load of a bus full of large scowling Bills fans, I think he filled his pants and then he beat a hasty retreat.
