One Saturday night when the girls have no dates, Fonzie drops by and asks them to babysit his godson and they agree. But when a date opportunity materializes, they play odds-and-evens to see who stays with the baby, and Shirley--who usually wins--loses. After she leaves, the guy calls to say he can't keep the date after all, so Shirley asks Lenny and Squiggy to go catch Laverne, but they refuse.
