Stephen Colbert is playing Homer's life coach. They're talking on the phone, as Homer is trying to fly a plane.
SC-"I''m not very good. I went to the Harvard of the South."
Homer-"Duke? That's good."
SC-"Not Duke."
Homer-"Vanderbilt?"
SC-"A little further south. Don't make me say it."
So I guess it's official. Duke is the Harvard of the South.
