This is the first time viewers see Lucy's bedroom or any of the rooms on the second floor of the Carter home.
Harry says that he promised to give Lucy a raise on her 40th birthday. In an earlier episode Lucy says that she's only worked for Harry for two years. Lucy is about to try to calculate her back pay but realizes that would mean disclosing her real age, so she takes an early lunch instead.
Alone in the office, Harry is nearly caught by his niece and nephew looking at a magazine centerfold. Although the cover of the magazine has been removed, the fold-out centerfold was a device used by Playboy Magazine, a publication that was famous for its photographs of nude or nearly nude women.
Victor Sen Yung, Spencer Chan, and Murray Pollack all appeared in the 1961 film musical "Flower Drum Song," based on the 1958 Broadway musical by Rodgers and Hammerstein.
When trying to think of a possible date for Lucy, Craig asks Kim who she [Kim] would like to date. Kim replies "I don't think mother would be happy with Ringo Starr." Craig then suggests Lawrence Welk. Welk was mentioned several times on "The Lucy Show" and guest starred as himself on "Here's Lucy."
