Chris Stevens' Masters' thesis defense in "The Graduate." He prepares a dense, deconstructive analysis of "Casey at the Bat," but over the course of the episode, comes to question this approach. At the appointed time for his defense, he summons his advisors to a baseball field, where he takes the role of the pitcher, and one of the advisors takes up a bat.
