Bad Tar Heels, Bad!

Anyone who's married or in serious relationship can vouch for the difficulty of mixed allegiances; when you're a Cardinals girl, it's gonna be difficult sometimes for you to deal with a Cubs boy. (And not just because of all the crying.) Yankees fans and Red Sox fans can't mate; it's against the law. There are just so many potential land mines.

And when you bring a kid into it? Look out. This boisterous rugrat has an N.C. State grad for a father and a North Carolina grad for a mother ... and it's clear which parent is winning the battle for loyalty. Mom, we'd suggest leaving the house next time the Pack and Heels play; something valuable's going to get dun broke.
