Some Mothers Do 'Ave 'Em

As experience for when he becomes a parent, Frank attends a father's class at the local maternity hospital, and afterwards pays a visit to his bank manager in an attempt to get some money, but is unsuccessful. Frank and Betty then take Betty's two nieces to the zoo, where an incident involving Frank and a monkey takes place, and then later to the rollerskating, where, on wheels, Frank leaves the rink and ends up on the open road.
