The title of the episode is taken from a song in the movie Funny Face (1957) sung by Fred Astaire & Audrey Hepburn.
Lorelai remarks after the movie ("Funny Face") that "Audrey Hepburn was 20, and Fred Astaire was like 80". For the record, Audrey Hepburn was 28 when the movie was made, while Fred Astaire was 58.
Lorelei always had New England favorite Red Vines but with the new show runner she has switched to the more common Twizzlers.
The title S'Wonderful S'Marvelous is a classic Gershwin standard that was introduced in the 1927 Broadway musical "Funny Face". The song was originally performed by the brother & sister team of Fred & Adele Astaire. The show was finally filmed 30 years later with Fred Astaire & Audrey Hepburn.
