Trivia: According to French Stewart during a 3rd Rock from the Sun reunion Q and A at the 2021 Vulture Festival, he and Joseph Gordon-Levitt could never get through the scene where Harry spits baby food at the baby without the two actors breaking character and laughing hysterically.
Trivia: When the Solomons meet the Big Giant Head at the airport and ask how his flight was, he says that it was horrible because when he looked out the airplane window, he saw something on the wing of the plane. Dick responds that the same thing happened to him. William Shatner appeared in the 1960's Twilight Zone episode "Nightmare at 20,000 Feet" in which a gremlin tried to destroy the wing of a plane. John Lithgow appeared in "Twilight Zone: The Movie" playing the same character in the same situation.
Trivia: Dick is never seen walking in this episode and is only in an upright position when he moves from the chair in the lounge room to the wheelchair in the opening scene. This is because John Lithgow hurt his ankle playing tennis, and the episode was written to allow him to be in a wheelchair for the entire episode.
Trivia: When Dick and Tommy walk through the Eversoll office, the door they open up has the name "Gary Parkinson." Gary was the Buckeye Fidelity insurance salesman from s05e03, "The Fifth Solomon." They also pass the office of "Ted Hughes." Ted also worked at Buckeye. Terry Hughes was the director of the episode.
Trivia: When Don and Dick are lamenting about their respective girlfriends posing nude for photos, they unwittingly recite some of the chorus lyrics to the song "Centerfold" by the J. Geils Band. A portion of the song's intro can also be heard during one of the episode's transitional animatics.
