during the eight-year run of "the andy griffith show" and the subsequent three-year run of "mayberry r.f.d.", the fictional mayberry county, north carolina, where mayberry was located, was established to have been a dry county. a running gag on the show portrayed the otis campbell character as constantly ending up in jail due to his drunkenness. otis was drunk so often, he would let himself into his regular jail cell using a key stored within reach of the jail's two comfortable cells and sleep off the effects of alcohol. many plots would also involve out-of-town criminals committing alcohol-related crimes, such as running moonshine in mayberry. in reality the only county in north carolina that is completely dry is graham county, which is on the tennessee border.
