The Andy Griffith Show (1960) : 7x23

When Howard suggests Mayberry erect a statue of Andy’s ancestor Seth Taylor in honor of all the work he did to make the town the quaint place it turned out to be. However, after a local artist completes the statue and earns the praise of the Taylor’s and everyone else in town, Andy and Aunt Bee get a big shock when Mr. Simmons lets them in on a secret that Seth Taylor worked with his ancestor to swindle the town out of a large amount of money. At first Andy and Bee want to keep this secret under raps, but she soon admits what Seth did during the unveiling speech. In the end, Floyd saves the day by saying that while Seth wasn’t the hero everybody thought he was; he still played a large part in making Mayberry the town what it is today.
