That is not a quote that will be found in this [pdf], a speech for the London School of Economics, delivered by David Graeber, an avowed anarchist. Graeber has just been shown the door by Yale, where he taught anthropology. Although he is broadly considered to be one of the great young anthropologists in the world, his outspokenness and activism apparently trumped his academic work in accounting for the no-rehire. Anyway, it's a fantastic speech.
The above quote does come from Seth MacFarlane (The Family Guy creator), who gave Harvard's Class Day speech. (youtube)

Part 3 (in Stewie Griffin's voice)
Part 4 (in Quagmire's voice—not really that funny)
The kid right behind MacFarlane is incredibly annoying. Watch out. (both items via Metafilter)
