Homer forms the Pin Pals, a bowling team made up of Moe, Apu and Otto, but the team has to cut Otto when Mr. Burns muscles in and insists on joining. Meanwhile, Principal Skinner implements a school-wide dress code when Bart shows up to school in a MAD Magazine T-shirt. The Pin Pals take on the Holy Rollers (Ned and Maude Flanders, Reverend and Mrs. Lovejoy) and other teams until they're in the finals. Even though he's no longer on the team, Otto manages to help the Pin Pals win the tournament. Getting caught in the rain, the children of Springfield Elementary School discover that their new school uniforms are not color-fast, and are amused by the wild colors their clothes make when wet.
