When Millie insists that the amphitheater needs more lights, she says to Fanny and Michelle, "More lights will make it beautiful. It HAS to be beautiful. Everything is beautiful at the ballet." "Everything is beautiful at the ballet" is a line from the song "At the Ballet" from the musical A Chorus Line. When Kelly Bishop (who plays Fanny) was in the original Broadway cast of A Chorus Line, "At the Ballet" was one of the songs she sang.
The woman who plays Michelle and Scotty's mother is only 14 years and 8 years older respectively.
The title of this episode comes from a line in the classic 1950s movie "Sunset Boulevard". A vicuna is a South American animal similar to a llama or alpaca. At the time the movie was made, they had been hunted to near extinction, so vicuna wool was rare and expensive. In the movie, William Holden's character finds himself in a dependent relationship with a much older movie star played by Gloria Swanson. A tailor/salesman, believing that William Holden's character is a gigolo, urges him to buy the most expensive overcoat, saying: "As long as the lady is paying for it, why not take the vicuna?"
