After Andy, Barney and Opie swap Aunt Bee's bad-tasting homemade pickles with some better-tasting store-bought pickles, they put the home canning jars that now contain store pickles back into the Taylors' kitchen cabinet. Barney then leaves the kitchen with a valise full of the bad homemade pickles in the store-bought jars. In the next scene, Barney is outside of town giving the motorist from Portland a home-canning jar of Aunt Bee's bad pickles as a Safe Driver Award. He should be handing out the store jars from the valise, not home canning jars.
At around the halfway mark, when Aunt Bee brings lunch to Andy and Barney in the courthouse, she is standing in front of Andy's desk and Barney is standing to her left. Apparently, the scene is done on two different days, because in the middle of their conversation, in the only close-up of Aunt Bee, when she says she has already told everyone she would be entering her pickles in the contest and now has none to enter since they had all been eaten, she looks totally different than the way she looked before and after in the same scene: her hair is swept up on the sides and arranged differently on top and her collar and partial blouse showing under it are different than the original look. Also, the tape quality is different in that it's clearer and darker than the tape quality in the same scene before and after that close-up. It's obvious that the close-up was added later into an already-filmed scene.
When the judges are evaluating the pickles, they're standing at a table before a background of shelves filled with other home-canned fruits and vegetables in glass jars. After the first prize is announced, the background shelves are full of cakes.
Throughout this episode, Aunt Bee refers to making a batch of pickles as making eight quarts. She tells Andy and Barney that they're the lucky ones because she made a double batch of sixteen jars. All recipes for a batch of pickles are for seven quarts, not eight, because seven is the number of quart jars that will fit in the standard, blue enamel, water-bath canner. This canner size has been the standard for at least the last half of the 20th century and probably even earlier.
When Clara visits Aunt Bee early in the episode, they discuss the fact that Clara has won the Blue Ribbon for the best pickles at the County Fair eleven years in a row. Aunt Bee says she is not planning to enter the contest because she has lost ten years in a row. Clara corrects her that she has lost eleven years in a row. However, Aunt Bee has not lived in Mayberry for eleven years. She arrived when Opie was a year or so younger.
This installment conflicts with the rest of the series in that Bee Taylor is known as an excellent cook.
