In this episode, as in some others in the series, Felix talks about his High School girlfriend, Mildred Fleener. He mentions here that she was his date the night of his High School graduation and Prom. In the episode broadcast a week earlier, The Odd Couple: The Odd Holiday (1973), he reveals that his ex-wife's maiden name was the same, when he sums up the tale of their breakup by telling Murray, "That's the story of Felix Unger and Gloria Fleener."
Felix uses the phrase "La Forza del Destino" (the power of fate) as a mantra in this story. As the title of an opera by Giuseppe Verdi, it is one of the answers to the radio station's opera quiz that allows Felix and Oscar to win their new car. Each time something happens with the car, good or bad, he repeats the phrase, reminding Oscar how Fate can influence their lives. He even translates it into German for Oscar: "Die Macht des Schicksals", which he varies slightly, saying "Die Macht das Schicksals". Oscar varies it even more when he tries to repeat it, with humorous results.
When the parking garage owner (played by John Byner) asks Felix and Oscar where they live, Felix says, "74th and Central Park West". That is the actual location of the San Remo, the apartment building used in the 4th and 5th seasons of the show as Felix and Oscar's building. In this episode, when the car, won in the radio quiz, is delivered - complete with ribbons and beautiful girls - the scene is filmed in front of the San Remo's main entrance, at 145 Central Park West.
