When graduation day arrives, college students usually want to fast-forward the ceremony to the moment they walk across the stage and receive that long-awaited diploma. Rarely will you remember which politician or scholar spoke at your graduation, but occasionally someone comes along that connects with the 20-somethings in the audience.

That's what happened in Massachusetts when comedian and actor Charlie Day returned to Merrimack College to give the commencement speech to the class of 2014.

"This year, you will get to receive wisdom, life lessons, knowledge, from a man who's made a living pretending to eat cat food," Day said as he opened the address.

Of course, Day's description of his career is extremely modest. He became one of the most recognizable faces in television as executive producer and writer for It's Always Sunny in Philadelphia, accomplishing much more than the 'Charlie work' he became famous for. That success was parlayed into movie roles with some of the biggest names in Hollywood.

While the speech was filled with the same self-degrading humor that has gained Day much of his notoriety, there was plenty of life advice sprinkled in throughout the 19-minute video.
