In the epilogue Karl Malden and Michael Douglas stand before a memorial plaque that reads, "In Tribute to the Police Officers of San Francisco Who Gave Their Lives in the Line of Duty." This plaque also appears at the beginning of Dirty Harry (1971).
Liza and Ted's apartment boasts two large art prints by Maxfield Parrish: "Ecstasy" and "Contentment."
The book on Liza's table when Ted writes his phone number is "Between Parent & Child" by Dr. Haim G. Ginott. Sadly, Ginott died on November 4, 1973, eleven days before this episode originally aired.
