You know you're supposed to wear green so you won't get pinched. You hope to find a leprechaun to lead you to a pot of gold. But did you know that St. Patrick didn't actually run all the snakes out of Ireland? The temperature of Ireland is actually too cold for snakes to inhabit!

Here are 10 more fascinating facts about St. Patrick's Day that you probably never knew.

1. St. Patrick wasn’t even Irish.
