When Barney is reenacting the crime, he tells Goober to sit in the chair, as he was probably waiting for a haircut. Then Mr. Foley walks in and Barney says that he must have gone straight to the chair, cutting in front of Goober.
Near the end of the episode, when Barney is bringing Goober to the courthouse with red light and siren, they pass the barber shop. A barber and another gentleman are standing in front of the shop and the barber is not Floyd. At this post-stroke time in his career, Howard McNear could not stand and was always seated when appearing.
Opie mispronounces Floyd's name, telling Andy that Johnny Paul "says Floyb was a crook."
