I recently saw a later episode of the Andy Griffith Show. It was in color and Don Knotts had left the show. Aunt Bea was selected for jury duty and was the lone holdout in a burglary trial where the other members of the jury were pressuring her to convict the defendant (a premise that has been used by a few sitcoms). Of course, she held out and hung the jury before it was discovered by Andy that the crime was committed by someone else.

What was interesting was that the minor role of the defendant was played by a young Jack Nicholson.
