In between jabs about the Wahoos snagging the top spot on Playboy's list of top party schools and personal recollections of doing some partying of his own with the girls of Phi Kappa Phi, Stephen Colbert had one pearl of wisdom to impart on the University of Virginia's Class of 2013: Feel free to be self-obsessed.
