Is this even a question? It's Vikings fans. They have NOTHING to brag about - ever. Yet somehow they manage to our annoying little brother. Their tactics are simple minded and infantile and big brother knows he shouldn't let it bother him... but it just does. All he can think about is punching the stupid annoying little brother out.
I can understand voting for Bears fans - they are jerks sometimes and refuse to see common sense. But at least they give (grudging) respect where it is due. And Lions fans are just such masochists it's hard to hate them. I thought about 49ers fans... but that's more their coach than them. Maybe Pats fans? But it's hard to hate someone we only play once every 4 years.
What say you Packers fans?
