Anyone who's ever been to an NFL game knows that Americans are no slouches when it comes to getting epically sloshed and rowdy at sporting events.
But believe it or not, we've got nothing on UK soccer and rugby fanatics.
These blokes earn the name "hooligans" at just about every match by guzzling pints and bashing their shaved skulls into one another regardless of whether their team wins or loses.
Needless to say, it's not the sort of affair that's necessarily fit for royals, or even royal in-laws, but that didn't stop Carole Middleton from (reportedly) getting a little tipsy at the England vs. Australia Rugby World Cup match at Twickenham Stadium in London.
Maybe it was the fact that England was bounced out of the tournament after a 33-13 arse-whupping. Maybe it's the fact that Pippa Middleton can't hold down a job. Or perhaps she's bracing herself Duchess Kate's third tumultuous pregnancy.
We like to think that Carole just felt like tying one on, so she did just that.
The woman is forced to live her life in the public eye, and she has constantly has to worry about pissing off the Queen.
If anyone's to entitled get proper pissed at a rugby match, it's Carole.
