A Tucker Telephone is a torture device invented in Tucker State Prison in Arkansas, using the magneto from an old hand-crank telephone. The ground wire was attached to the big toe, the hot wire to the genitals, and crank away. A "long distance call" was an extended series of shocks. The scene depicted in the movie "Brubaker" was a good portrayal of the real practice. "Brubaker" was a realistic portrayal of life in Cummins and Tucker Prison Farms in Arkansas until the prison reforms of Gov. Winthrop Rockefeller. A variation of the Tucker Telephone was used an an interrogation tool in Viet Nam and Abu Graib using stripped-down field telephones. It is still commonly used all over the world.
