After trying a new shampoo for the first time, Dewey mailed off an enthusiastic letter of approval to the manufacturer.
Several weeks later he came home from work to a large carton in the middle of the floor. Inside were free samples of the many products the same company produced: soaps, detergents, tooth paste, and paper items... with a "thank you" note from the manufacturer.
"Well, What do you think?" asked his smiling wife, Olga.
"I think that next time," Dewey replied. "I'm writing to Toyota".
