The residents of Hooterville are in an uproar when Arnold Ziffel the pig is missing.

Lisa reminds Oliver that he promised her a New York vacation if she stayed with him on the farm for two years.

When an expectant mother goes into labor, Oliver takes her to the hospital, and Lisa takes her seven other children to live with the Douglases until she recovers.

Lisa cons Oliver into taking a 'fifth' honeymoon together, this time in Hawaii. When they check into the honeymoon suite, they are unaware that the hotel manager's daughter, has given her friends the suite for their honeymoon also. Since the suite has two bedrooms it's just a case of both couples avoiding each other while on their honeymoon(s), for a while anyway.
