The escaped convict (Allan Melvin) outwits Barney and Gomer by turning his head and speaking in a disguised voice. Allan Melvin voiced many cartoon characters. This performance 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.
Allan Melvin appeared eight times on The Andy Griffith Show (1960). Each time as a different character.
At the beginning of the episode, Andy mentions a geographic location in the County of Mayberry: Snakeskin Creek.
