Dick accompanies Mary and Nina to a book-signing for a self-help book entitled 'A Road Map to Happiness', and despite first thinking it stupid, Dick opens the book and is immediately converted. He then concludes that his relationship with Mary stands in the way of his happiness, and attempts to break up with her. At college, Tommy is attempting to get into a fraternity but is doubtful that he'll pass the entry rituals, so he enlists Sally's help, but she just ends up making it harder.
