I hate the Vikings for more reasons than one...but 2000 they became the enemy for me.
Cowboys...I wasn't allowed to eat at my dad's table if I was a cowboy fan. I remember for christmas...my Grants got me and my brother cowboy pj's and winter caps and starter sweatshirts with the cowboy star galore. My father politely gave em back to my grandmama.
Rams...the No Call...I hate them more than the Falcants actually.
