When a band of roving gypsies stop off in the Mayberry area, Andy warns them that if they misbehave he'll ask them to move on. Sure enough, they're soon selling shoddy products and false hopes and Andy has no choice but to tell them to move on. Before they leave however, they place a curse on Mayberry saying there will be no rain. Mayberry has already been going through a drought for several weeks now and people are getting a bit short-tempered. What no one knows is that the Gypsies have their own special sources of information when it comes to the weather.
