"DON'T MESS WITH TEXAS!"
I was at a Cubs gamee, yes, a Cubs game, one time and there were a group of guys with Texas shirts and hats and stuff and you could tell they were from Texas, not just posers, and, of course, drunk off their asses. I screamed "Don't mess with Texas!" and they just went nuts! Hootin' and hollerin' like cowboys. I had a good laugh over that!
