Steve: So what's Denver like, dad?
Stan: Well, it's two thousand miles above sea level, so the winds are fierce. Hence its nickname, "The Windy City."

Hayley: Dad, you can't let Steve and Roger stay in the tree house. They'll catch their death.
Stan: Nonsense. Death has better things to do, like remembering Tony Curtis already.

Steve: Wait, Dad, you can help me with my report?
Roger: (whispering) Uh, Steve, I don't think that's a good idea. Your dad is kind of a moron.

Steve: This is the New York stock exchange!
Roger: Like in the movie Wall Street?! I thought that was Hollywood make-believe, like children of every color being at the same McDonald's.

Steve: Then, in 5000 BC, a mere 1,000 years after the creation of Earth, the Human-Dinosaur Treaty fell apart and they drove the dinosaurs underground, and that's where fossils come from.
Teacher: (under his breath) Dumbass.

Francine: What's going on?
Steve: I can't live under the roof of a man who's forcing me to walk in his ignorant footsteps.
Roger: And I can't live under the roof. Literally, I live right under the roof, and I hate it.

Klaus: (Dressed as a cat; sitting on Roger's lap) It's fun to play dress-up. Not all the time, but sometimes. Not this time.

Steve: Kudos to the way you conned my dad into getting us this popcorn machine.
Roger: It was just a matter of finding the right way to combine the words "tasty," "low-fat," and "9/11."
Steve: Speaking of 9/11, I believe that was my dad's SAT score.
(Both of them laugh)

Steve: Now to just type "fossils" into the search engine. And now to just separate the fossil sites from the porn sites. "Tyrannosaurus": fossil. "Babe-a-sore-ass": porn. "A Symposium on the Pangea Theory of the Permian Extinction"...Wow, that is some nasty porn!

Stan: That is so Raven!

Stan is putting a spin on the name of Dinsney Channel's hit original show, That's So Raven, which he is apparently watching.

Irregarding Steve

The episode title is a spin on the title of the movie Regarding Henry.

The Spy Who Loved Me

Klaus' dream sequence scene with him and Francine driving under water after their car turns into a boat is a spoof on a scene from the James Bond movie: The Spy Who Loved Me.

Klaus also states that he found Atlantis. The lost city of Atlantis is from the legend of the great city of Atlantis, which was supposedly lost to the bottom of the ocean.

Gilbert the Squirrel: Ha ha! Mama's hiding from me!

The entire co-plot with the squrriels is a direct reference to the movie What's Eating Gilbert Grape?. Everything, including actual lines, characters/character names, looks & hair styles, movements, and plot events were taken from that movie.

Roger: Like in the movie Wall Street? I thought that was Hollywood make-believe, like children of every color being at the same McDonald's.

Wall Street is a real movie from 1987, directed by Oliver Stone.

McDonald's is one of the most famous fast food restaurants in the world.

Roger: It was just a matter of finding the right way to combine the words "tasty," "low-fat," and "9/11."

9/11 is a reference to September 11th, 2001, when two planes taken hostage by terrorists were flown into the World Trade Centers.

Klaus: (Dressed as a cat; sitting on Roger's lap) It's fun to play dress-up. Not all the time, but sometimes. Not this time.

The way Roger is sitting when Steve walks into his bedroom is much like the way Dr. Evil from the Austin Powers movies would sit with his cat.

Stan: Nonsense. Death has better things to do, like remembering Tony Curtis already.

American actor Tony Curtis' (1925-2010) is mentioned in this episode. At the time the episode aired the joke of course, was Death paid close attention to Tony Curtis.

Midnight Cowboy

The entire Steve & Roger plot is based off the movie Midnight Cowboy.
