Jerry is pressured into visiting a sick fan who lives in a plastic bubble on the way to a cabin upstate. Due to a driving error, George and Susan arrive at the house first, leaving Jerry and Elaine lost at a diner.
George begins playing Trivial Pursuit with the Bubble Boy, who turns out to be incredibly obnoxious. A violent dispute breaks out over a misprinted card regarding the invasion of Spain by the Moors (or “Moops”), resulting in the bubble being compromised.
