The escaped convict outwits Barney and Gomer by turning his head and speaking in a disguised voice. Allan Melvin voiced many cartoon characters. This was a rare live action display of that talent.
Andy is reading the January, 1963 issue of National Geographic when Barney and Gomer come to the window.
At the beginning of this episode, Andy mentions a geographic location in the county of Mayberry, Snakeskin Creek.
