Stephen Colbert's 2006 Commencement Address at Knox College:
"Today is about you—you who have worked so hard to pack your heads with learning until your skulls are all plump like—sausage of knowledge. It’s an apt metaphor, don’t question it. But now your time at college is at an end. Now you are leaving here. And this leads me to a question that just isn’t asked enough at commencements. Why are you leaving here?"This is an instant classic.
