At the end of the episode, Don and Ann are playing charades. In a nod to the popular culture of the day, Ann chooses to use Valley of the Dolls as a book clue with four words in its title. The book itself came out in 1966, and the movie came out in 1967. Don uses the 1963 Elizabeth Taylor film Cleopatra as his clue for a movie with one word.
The picture in the frame hanging on the wall in Ann's bedroom is a copy of Andrew Wyeth's "Christina's World." The Christina depicted in the painting was an actual person, Anna Christina Olson, who suffered from a form of polyneuropathy and, by all accounts, inspired the painting when Andrew Wyeth, had taken up residence nearby the Olson farm and had spotted Christina, who was unable to walk, crawling her way across a field on the Olson farm. In fact, Christina and her brother Alvaro were the subjects of many of the artist's paintings. The model for the body in the painting was not, however, Christina, but the painter's wife Betsy Wyeth.
Jerry suggests that Don will love it in Paris and mimics Maurice Chevalier singing "I Remember It Well" from the Alan Jay Lerner and Frederick Loewe musical Gigi (1958).
