The Andy Griffith Show

The Gypsies (6x23)

Air date: Feb 21, 1966

Andy orders a group of gypsies out of town after they bother the residents. They soon set up camp outside of Mayberry and place a "curse" on the area in the form of a drought. Everything's later revealed to be nothing more than a hoax, as the gypsies are using a radio to enact their scheme.
