Dr. Katz gets the sudden urge to play the board game "Guess Who" with Ben. During the game, Katz sees the reflection of Ben's pieces in the TV screen and guesses correctly, annoying an oblivious Ben. Katz eventually comes clean about cheating, and offers to leave the apartment for a night as self-punishment. But in the process of saying where he'll probably be staying (the Hilton), Ben wants to come along.
