Leonardo, Donatello, Michelangelo, and Raphael will be celebrating their 33rd anniversary next month, and during those 33 years our heroic Teenage Mutant Ninja Turtles have fought a lot of crime, and eaten a lot of pizza.

As fans of the comic and show, we may have done significantly more of the latter than the former, but we also learned a lot about life from our favorite foursome (are we allowed to say they’re bigger than The Beatles, because we don’t recall The Beatles ever fighting crime on a regular basis).

It may seem odd to draw conclusions about life from a set of comic book/cartoon characters, but hey, we’re a little odd, so hop to the next page and check out 12 life lessons we learned from the Teenage Mutant Ninja Turtles.
