While cleaning the jail cell, Andy tells Opie that the jail doesn't have many customers "since Otis started doing his drinking in Mount Pilot." The character of Otis had been dropped from the show early in this same season, reportedly because a sponsor objected to their products being associated with a funny town drunk. But in the 1986 reunion special "Return to Mayberry" it was revealed that Otis had successfully stopped drinking and was now driving an ice cream truck.
Hal Smith, the actor who played Otis, continued to have a thriving career on TV, especially as a voice actor In animated shorts. Among many other roles, he supplied the voices for Disney's 'Goofy,' and for 'Owl' in "Winnie the Pooh."
