It’s commencement season at institutions of higher learning around the country and colleges are rolling out the most important and/or famous people they can find to inspire students who are probably too hungover from the night before to realize their robes are on backwards. At Merrimack College in North Andover, Massachusetts, alumnus Charlie Day of It’s Always Sunny in Philadelphia fame gave a fantastic 18-minute speech that might be the only commencement speech in history to feature the phrase “I don’t give a shit.” It may also be the only commencement speech to acknowledge that most of the students in the audience are, at that moment, drinking wine out of a coke can. But between all the jokes and uncomfortable laughter from the serious academic sitting behind him, Charlie gave a speech that proved even a self-proclaimed “guy who pretends to eat cat food for a living,” has valuable life lessons to teach. Most importantly, if you are ever given the choice between scraping together a project you’re passionate about or starring in a network TV show about selling hot dogs, never choose the hot dogs. If you graduated from college, or plan to someday, the video is worth a watch.
