This episode is the hands down winner of the Jump the Shark award on the www.jumptheshark.com, meaning this episode, for most fans, marks the point where the series began to decline. Obviously the reason most fans cite is the loss of Don Knotts as a regular cast member. In addition, the writers changed and the entire tone of the series changed dramatically. Andy's first appearance in this episode (he's quite grumpy!) makes it very clear that the jolly, easy going Andy of the early seasons is gone.
In this episode Goober tells Andy that Frank brought his car into the station, stating that it needed a new fuel pump. However, in the epilogue Helen tells Andy and Aunt Bee that Frank returned to Raleigh on the 4:00 train. If Frank had a car, why would he need to take the train back to Raleigh?
This episode marks the final appearance of both Ernest T. Bass and Malcolm Merryweather. Ernest T. would have a major role in the television movie "Return to Mayberry" but Malcolm, who chose to live in Mayberry, is never seen again.
Ernest T. is working as the school crossing guard to save up enough money to marry his sweetheart he calls Romeena - Romeena is actually Romona Ancrum whom Ernest T. met at Ms. Wiley's in the episode "My Fair Ernest T." We never find out if Ernest T. ever married Romeena. In the television movie "Return to Mayberry" she's never mentioned and Ernest T. seems to be sweet on Charlene again (Dud must have passed away).
This episode marks the first appearance of Jack Burns as deputy Warren Furgeson. Warren, who only lasted a few episodes, was the show's only real attempt to replace Barney Fife.
Although legally bingo might be seen as gambling, there are numerous legal precedents where charity bingo and raffles are permitted by state and federal law.
The article "Sheriff Without a Gun" was first mentioned in season five's "TV or Not TV." In that episode, bank robbers posed as television producers producing a television series based on the article. Despite the fact that Andy typically does not wear a gun (like Barney and Warren) he does often use guns when on manhunts and other dangerous work and even once shot a man attempting to rob a service station.
One of the prizes Aunt Bee kept was the garbage disposal, but in "Lost and Found," she does not have it, and buys one.
In this episode it is mentioned that the Mayor is on vacation in in Hawaii. It seems odd that the Mayor would schedule vacation during Founders Day (typically a rather large event for Mayberry). The mayor's name is never mentioned but it doesn't seem likely that Mayor Stoner (last seen in season 3) would be out of town for a big even like Founders Day.
Aunt Bee states her birthday as March 17
With Warren going after Helen in his sleep, a flustered Helen locks herself in the jail! This is the only time we would see Miss Crump in the cell!
In this episode, Barney drives into Mayberry in his "new" car, a turquoise and white Edsel convertible. Andy inquires if the car is a '61 model. Barney replies that it actually is a '60 but it has a '61 grill. This is all totally wrong. The car is a 1958 Edsel. It has a 1958 grill and there was never a '61 Edsel. They started production with the 1958 model year and were discontinued after the 1960 model.
Sweet Nettie fetchingly stares right into the camera for an instant as she's delivering her dialogue to an off-screen Barney. Was this a goof or charm? You decide.
When Aunt Bee shows everyone the "missing" pin, Andy puts it on Bea's lapel. Later, when Warren and Goober are discussing the whole mess, the pin is sitting on the dining room table. When did Aunt Bee take the pin off?
Aunt Bee buys a garbage disposal, but in "Aunt Bee on TV," a garbage disposal was one of the prizes she kept.
Not only did she learn to drive, but Aunt Bea was the only main character who learned how to fly on the show.
It seems unusual that Aunt Bea is nervous around baby, because in the first episode she said "I raised all those kids".
This is the first appearance of the character of Howard Sprague.
