Trivia: Throughout the series, a number of times Fred mentions "Pluto water." It was a popular strongly laxative natural water product that was sold until 1971, when production and sales halted because lithium, one of the mineral salts, was declared a controlled substance. Sanford and Son debuted in 1972, so Fred couldn't have had this product throughout the series.
