Dick's Big Giant Headache (1) - S4-E23
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.
Tricky Dick - S3-E3
Trivia: Dick's rant about his perceived evils of rock music is identical to Reverend Moore's (also played by John Lithgow) opposition to dancing from the film "Footloose."
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: Kristen Johnston kept the gnome statuette that was in the Solomon's attic apartment after the series concluded, but claims to have lost it.
Trivia: French Stewart kept Harry's signature fur coat after filming of the series concluded. In his own words, he stole it.
Trivia: Katherine LaNasa, the actress who plays the woman that Harry gives the dog to and subsequently hooks up with, was French Stewart's first wife. They met filming this episode.
Trivia: Leon is played by John Lithgow's real life son, Ian Lithgow. Although he is often portrayed as a somewhat dim-witted college student, Ian had already graduated from Harvard (like his father) prior to the series starting.
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.
This Little Dick Goes to Market - S5-E14
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.
Fifteen Minutes of Dick - S2-E23
Trivia: At the book signing with Mark Hamill, a poster of the comic "Black Pearl" is displayed. Mark Hamill created and wrote "Black Pearl."
Trivia: Al Franken appears in this episode as a slimy politician. Franken would become a politician later in life, serving as a United States Senator for Minnesota. He ended up resigning in 2018 after photos surfaced of him on a USO tour pretending to grope the breasts of radio host Leeann Tweeden while she was asleep.
Trivia: One of the reasons John Lithgow agreed to star in this show was because he wanted to have something to do other than playing "cornball villains."
Trivia: This episode marks Phil Hartman's final onscreen role in his lifetime. He was murdered 8 days after it aired.
Trivia: When Sally is giving everyone instructions to look for the missing Dick, her speech mirrors that of Tommy Lee Jones from The Fugitive (searching every outhouse, hen house, doghouse, etc). She even mimics his Texas accent.
