St. Patrick's Day is a real test day for relationships. I've gotten in some brutal relationship fights on the day because you're all LET'S DRINK EVERYTHING ALL DAY EVEN THOUGH WE'VE BEEN HOLED UP ALL WINTER and then things might happen.
This couple was clearly in the middle of such a fight, in front of lots of people, and the guy is so miserable in the fight he decides the best option to win it would be to slam his head into a window.
Spoiler alert: I don't think it worked.
