Vivian plays piano, just as Ethel did on I Love Lucy.
Lucy pulls out a violin, saying she used to play it in school.
(Viv helps put up busts of famous composers to convince Sam she's a classical music fan)
Viv: Lucy, do you really think all of this is going to prove you're a big music lover?
Lucy: Well, it'll create a mood.

Chris is once again a Bobby Darin fan. She'd smashed all of his records recently when he got married.
This episode marks Mary Jane Croft's first appearance as Audrey Simmons, a character not unlike Betty Ramsey whom she played on I Love Lucy. Audrey eventually will disappear from the series, but Croft will return, this time playing Mary Jane Lewis.
