The Andy Griffith Show
In this episode, the town named Juneberry and Sheriff Dandy Griffith are parodies of the 1960-68 TV series that featured the town of Mayberry and Sheriff Andy Taylor. The Andy Griffith Show is about a widower (portrayed by Griffith) who raises his young son (portrayed by Ron Howard) with help from Aunt Bee (played by Frances Bavier) and keeps law and order in the fictional small town.
