Barney spends his life savings to buy a used car. Unbeknownst to him, the car is actually a lemon and has several issues and defects.

Malcolm Tucker, a wealthy businessman, has trouble getting his car to start and finds himself stranded in Mayberry on a Sunday.

Barney organizes a rescue party when Andy and Helen become trapped in a cave after it collapses. Unbeknownst to Barney, the two have already escaped, but decide to go back into the cave to save him from becoming a laughingstock.

Barney and Gomer are responsible for watching over two thieves who are temporarily jailed in Mayberry. Between the two of them, the criminals manage to escape three times.

Barney orders Gomer and Otis to keep watch on Andy when an ex-con Andy sent to prison many years before returns to Mayberry.

Andy uses common sense and Barney uses modern technology to solve several burglaries at a filling station.
