Doonesbury by Garry Trudeau for April 06, 1971
Mike: Well, Rufus, I hope this is the beginning of a rewarding teacher-student relationship... Rufus: Fat chance! You don't fool me, Doonesbury! You're here because you think you're touching on the black experience! In addition, you strive to relieve your guilt feelings! Mike: Nonsense! I don't come here to relieve my guilt feelings! Rufus: Then why, man? Why do you come down here? Mike: I'm paid.
