Man, I remember getting a free ticket from the Vikes for that game that was rescheduled to Ford Field. They basically bribed people to be Viking fans for one day, and weren't above pleading. I had no issues with it, I like the Vikings alright, they're by far the most tolerable of the Lions' division rivals.
Which, with the bridesmaid thing, kind of reminds me of my uncle Lester. We often joked that you could tell what era each of my uncles grew up in because they all latched on to the big popular sports team du jour (I grew up in an area that was on the verge of like four fanbases). A couple were big Yankees fans, and another was a fan of the Dolphins because he was a teenager during their undefeated season. But my uncle Lester was not only a Vikings fan, but, as we later discovered, actually became one during a time when the Vikes were not very good. Why? Because he was sick of his brothers wholeheartedly bandwagoning and just picked a random team that wasn't good...in fact, he picked Minnesota in general and supported the Twins too, who also weren't very good at that time.
So I've always had some respect for the Vikings just because of the fact that he was my favorite uncle and his logic was pretty sound. He was also the only one that didn't stop being a fan during lean years (while the others wouldn't switch to other teams, they wouldn't wear gear or anything during the bad times).
