Excuse Me, May I Cut In? - S2.E4

Laverne and Shirley's tv breaks down, and when the contest offering a prize of a new color set arises Shirley acts nice to Richie Cunningham so that he'll ask her and Laverne to the dance, but also the real reason is that they want Richie to ask his friend Potsie Weber, who happens to be the school's best dancer, to partner Laverne. Potsie gets injured and can't dance so Laverne teams up with Richie at the last minute to win the TV. When back at the flat, the girls have to come clean about them just wanting the TV, but the guys are so nice about it that they get a little of what they were hoping for anyways.
