Oliver wants to have a simple, romantic Sunday picnic with Lisa. His afternoon for two turns into an irritating crowd when everyone invites themselves and tags along. Joining the couple are Eb, his girlfriend Linda and her accordion, her parents, Sam Drucker, his date and her sousaphone, Hank Kimball, Linda's Grandpa and some old lady he hit on at the gas station. That night, Oliver and Lisa take refuge in the barn when the crowd shows up at their house.

With just two weeks until their wedding, Eb and Darlene still don't have a location for the ceremony. Mr. Haney's first suggestion, to have it for free at a car wash, doesn't wash. His second scheme, which comes complete with a household of furniture, gets Eb's signature on the dotted line. Darlene's father, however, refuses to let her get married on television in a furniture emporium's front window.

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.
