Trivia: There were no American planes shot down over the Sea of Japan during the Korean conflict. It is rumoured that producer/director Larry Gelbart knew that, but wrote Henry Blake's death scene as he was very unhappy with the way Mclean Stevenson had left the show, and was determined to make it clear that there was no way he would be coming back.
Trivia: While Bob Newhart is a father himself, he was adamant about Bob Hartley not having any children. When the writers told him they wanted to introduce a child in season six, he told them the script was good, and then asked them who was going to play Bob.
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.
Trivia: The "lift voice" heard during the theme song in each episode is that of Stephanie Gathercole, who played Mr. Rumbold's secretary in the earliest episodes.
Trivia: Conrad Bain's twin brother Bonar makes an appearance.
