Andy and Barney are working late one evening to complete the county inventory. They've told Thelma Lou and Helen that the inventory has to be completed that evening if they are all to go to the dance the next night. Barney however runs into their old friends Daphne and Skippy - the Fun Girls - and they're soon both at the courthouse looking for a good time. Andy flat out refuses to go along and decides to give them a ride home to Mt. Pilot but sure enough, Helen and Thelma Lou see them all getting into the squad car. They refuse to go to the dance with them so Barney arranges for the fun girls to be their dates.
