In the opening sequence, Daniel Sousa was heard saying "That's the 64 dollar question". "The $64 Question" was an NBC radio quiz show that debuted in 1950. The events of this season take place in 1947. However, the phrase originated on the game show "Take It Or Leave It," which premiered on CBS radio in 1940 and continued its run until July 27, 1947 (shortly after this episode is set), when it moved to NBC. The game show changed its title in 1950 to "The 64 Dollar Question".
