Archie and Veronica go into hysterics at a bad old joke from Mr. Lodge ("What's a Grecian urn?"), causing Lodge to think that every joke he tells will inevitably crack people up.
Archie suggests that to learn to be more tolerant of each other, the gang should play "switch," where each person pretends to be someone else and tries to see the world through his or her eyes. So they draw names to find out who they're going to be, and Veronica becomes Jughead, Jughead become Reggie, Reggie becomes Betty, Betty becomes Archie and Archie becomes Veronica.
