You may know Charlie Day from his role on "It's Always Sunny In Philadelphia" or his various film projects.  On Sunday, he was not just an actor, he was also the commencement speaker for Merrimack College's graduating class of 2014.

Charlie used his signature comedic style to give one of the best commencement speeches I've ever heard. Between the jokes, Charlie gave a very inspirational speech to these new graduates.
