Shirley is waiting anxiously for Laverne to come back from the bank with their savings for their cruise holiday that they have been planning on for weeks. When Laverne comes in, she tells Shirley that they have $50 less than they thought, and now they're not going to be able to take the cruise as they only have two days until the ship sets sail. The girls get depressed until Laverne says that they shouldn't give up hope, that they still have two days left and that they'll think of something to come up with the money. The girls go see Carmine who gets them a job at J&J Shoes. Carmine tells the owner he'll bring all his tap dance students over to his store to buy their shoes if he hires Laverne and Shirley for the weekend. The guy hires the girls and tells them to go and get changed into their uniforms. When we see Laverne and Shirley again, Shirley is dressed as Jack and Laverne is dressed as Jill from the nursery rhyme. The store owner tells them they'll get $2 for every pair of shoes (thetvdb.com)
