As videos begin to surface of this past weekend's numerous university commencement speeches, there is only one that is worth reliving graduation for: Charlie Day, who plays Charlie Kelly on It's Always Sunny In Philadelphia, gives a meandering, goofy speech to Merrimack College that results in one important lesson: don't be afraid of failure.

The speech is full of Charlie Day humor: "I sound like a ten-year-old with a smoking problem" and, after acknowledging that Merrimack—his alma mater—had granted him an honorary PhD, "I plan to begin writing my own prescriptions immediately."

The real takeaway, though, is that fear shouldn't stand in anyone's way. In a rare moment of gravitas, Day closes his speech with sincerity and encouragement, confirming his earlier maxim that "I'm much smarter than the character I play on TV."
