Betty Jo's Bike - S3.E34

Betty Jo wants to buy her friend Willie's motorized bicycle. Kate says she can if she is able to come up with the money. Betty Jo gets a babysitting job on the condition that Kate is around to supervise, to which Kate reluctantly agrees. Kate winds up doing most of the work. Now many other babysitting offers and many other babies come out of the woodwork. Unfortunately, the jobs are all for the same night and under the same condition of Kate supervising. With help from the family, they make it through the night. Willie says he'll trade his bike for the family dog, but Betty Jo refuses.
