Dub Taylor guest-stars as Ben, the brother-in-law of Mayberry's fix-it man Emmett Clark. Conspiring with Emmett's wife Martha (
Mary Lansing), Ben tries to convince Emmett to go into the insurance business. Soon, however, Martha realizes that Emmett will never be happy without a hammer or screwdriver in his hand. First shown on January 8, 1968, "Emmett's Brother-in-Law" was written by a decidedly pre-
Taxi James L. Brooks. ~ Hal Erickson, All Movie Guide
