Jack Benny Show Titled Jack & Mary Go Christmas Shopping. Original Air Date Was 12/19/1943. This was during the final season of the "GRAPE-NUTS PROGRAM" (General Foods, Jack's sponsor, replaced "Jell-O" with "Grape-Nuts" in the fall of 1942 because the shortage of sugar during World War II limited Jell-O's availability). The script is by Sam Perrin, Milt Josefsberg, George Balzer and John Tackaberry. Butterfly McQueen appears as "Butterfly"; John Brown [who had previously been a part of Fred Allen's cast] is "Mr. Brown"; Frank Nelson, of course, is "The Floorwalker"....
