I did once years ago. I had no idea she was a Packers fan until football season started and she wore a Farve jersey...Luckily for me she was a hoe and I found out soon enough to get out of that realtionship.
I dated a packer fan for quite a while. She wasn't your typical packer fan though. She was hot, really smart and funny. The season was always interesting because we would make bets on the Bear/packer games. The great thing is that they always ended with us having sex...
