Rigsby invests in a white sports car to impress Ruth and takes her to the country club in it. On their return the car is severely dented and carrying part of another car with it. When Rigsby learns that the other driver, Mr. French, is a magistrate and will be calling at the house in the evening, he panics and tells Alan he can have the car. Mr. French duly arrives and, on learning that Alan owns the car, gives him ten pounds as it was actually Mr. French who caused the damage.

Exotic dancer Marilyn moves into the house with Charlie, a python that she uses in her routine.

When Douglas the curate comes round for his singing practice with Ruth, Rigsby decides to play a joke on them with the toy python but of course he ends up handling Charlie.
