Juneberry is a play on Mayberry, and Sheriff Dandy is a reference to Andy Griffith. Don Knotts is playing a character similar to his Deputy Barney Fife character from The Andy Griffith Show, despite going by his real name. The town of Juneberry doesn't look like Mayberry because they were reusing backgrounds, but they do have a midcentury town hall building that was clearly meant to mimic the Mayberry town hall/sheriff's office.
