The title is the name of an episode of NBC's old "wacky aliens look at our culture through their eyes sitcom", Third Rock From the Sun which starred the amazing John Lithgow and seemed to fit. I came across (stumbleupon.com) Lithgow's speech to the 2005 graduating class at Harvard. I highly recommend it!
Lithgow includes everything you want in a speech such as: humor (but not too much), social commentary (but not too much), and personal anecdotes that reflect his advice to the graduates ("be creative, be useful, be practical, and be generous").
Instead of telling the audience how he achieved fame and success as an actor, he explained how he used his acting career to launch a "concurrent second career" as a children's entertainer with a "secret agenda" to instill a love for the Arts in young people.
