I'm not much of a sports fan, but I heard this on GSN last night and thought it was funny. There's this live game show where you have to call in answers from home, or text msg, and they also accept e-mails.
They asked the ladies to e-mail in their favorite football teams. Now bear in mind the host is British, so she wasn't familiar with the teams. Someone mailed in they were a GB Packer fan, the host was asking if the e mail was serious, and thought the Packers were a joke e mail. She went on about it being a silly name for a sports team...then she came upon the part of the e mail about the fan being a dyed in the wool cheesehead, and she laughed out loud.
Would have been pretty funny if there were some Bears fans watching.
