This episode was shot and aired in 3D.
This episode, and the previous episode, have the Solomons dreaming for the first time. However, Harry actually first dreamed in Season 1, Episode 2 ("Post-Nasal Dick") when he dreamed about Martha Stewart.
French Stewart's dream/dance sequence can be found online.
In the dream sequence -- where Harry sings and dances to a song called "Life's Been Good To Me" -- Randy Newman appears as the piano player. I'm guessing that Randy Newman also wrote the song, which certainly sounds like a Randy Newman song. And the end credits include a "Special Thanks To Randy Newman." (Tjn - 12/29/2022)
