Continuity mistake: In 1-2: "Post Nasal Dick", Harry has a dream about Martha Stewart. But in this episode they panic because they dream and have nightmares and don't know what they are. Shouldn't Harry have panicked when he dreamed about Martha Stewart?
Other mistake: When Harry spits baby food on the baby (the camera lens in actuality) in retaliation for the baby spitting food on him and Tommy, Joseph Gordon-Levitt breaks character and laughs uncontrollably and looks at and gestures to off-screen crew members a couple times.
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.
[The Solomons are doing their taxes for the first time.]
Dick: Alright, Form 10-40. First name: Dick. Last name: Solomon. And Mary said this would be complicated.
Sally: Dick this is so boring. Why are we doin' it?
Dick: Because Sally, this is what humans do. It's like their national pastime. And you don't want us to stand out.
Harry: Hey, you know what'd be funny? Where it says "Sex," write "frequently."
Sally: That's a good one Harry.
Dick: They don't ask for your sex here.
Harry: Hmm. Well if there's any place that you can indicate that you like to have frequent sex, I think it's worth doing.
Sally: Farm income or loss. So did our farm show a profit last year?
Dick: No, we're Schedule F.
Tommy: Wait wait, we didn't have a farm last year.
Harry: We lost the farm? No!
Dick: Line 14, other gains or losses.
Tommy: I gained two lbs.
Sally: I lost my virginity.
Harry: Hey, there's your opportunity for that frequent sex thing if you wanna just throw it in.
Dick: Enter itemized deductions from Page 3, Schedule C, Line 2 to the extent they are allowable on Schedule A Form 10-40 NR.
Sally: Enter the larger of your itemized deductions from Line 28 or standard deduction shown on the left. My left or its left?
Tommy: See Page 30 to find your standard deduction if you've checked any box on Line 35-A or 35-B or if someone can claim you as a dependent.
[The entire family is shown to be very confused and the scene transitions to a short time later.]
Harry: I'm telling you, there is no Schedule B.
Tommy: There has to be, dammit!
Dick: I don't understand this, I'm a superior being. I can calculate the decaying orbit of a dying moon to within a tenth of an inch. Why can't I calculate the subtotal of Line 59-A? Why can't I find Line 59-A? Where the hell is Line 59-A!?
Sally: Calm down.
Dick: [begins tearing up his tax forms.] I can't take this anymore! I hate it! I hate it! I hate it! I hate it! [Suddenly finds Line 59-A.] Oh here it is. Everybody just settle down.
