This past Saturday, SantaCon took over New York City. For all of you unfamiliar with this classic American holiday, it's an entire day dedicated to dressing up like Santa Claus and getting a little crazy frolicking around with fellow Saint Nick look-a-likes. It's sort of like a massive Christmas flash mob that makes you feel like you're in a strange alternate universe, but it's actually totally awesome.

But when thousands of Santas take part in these sorts of shenanigans, weird stuff is bound to go down, right? You betcha! This festive free-for-all is the ideal time for bearded dudes and decked out chicks to go a little overboard in the drinking department (or they're just naturally nuts), and luckily for us, hilarious evidence of said shenanigans are up on Instagram and Twitter.

Check out some weird things that went down at SantaCon 2012.
