The animation of the building being demolished during the movie Arthur and Buster watch is from D.W.'s Baby. It was also previously reused on Meek For a Week.
When D.W. put on the incandescent light bulb, from the play that Mr. Ratburn's class did in Francine Frensky, Superstar, Arthur calls it his costume. But Arthur wasn't the incandescent light bulb, he was the phonograph. Buster was the incandescent light bulb.
(Jane checks her phone book. Then she picks up the telephone for her call.)
Man on phone from TV: Back to the petting zoo with you, kitty cat.
Jane: (crossily) Arthur!
Arthur: (holding one of D.W.'s doll's dresses) I think you're clothes have really, really shrunk.
Muffy: Arthur, I don't care what the holiday is, I just want to sell the t-shirts and souviniers and stuff, so will you sign this contract to make me the official seller of stuff?
Arthur: (groans) We don't even have a holiday yet, and already it's too commercial!
Binky: (whispering) Hey Arthur, about this whole holiday scam...
Arthur: It's not a scam Binky, it's an honest-to-goodness attempted to do something that is worthwhile.
This is the second appearance of Grandma Thora as a little girl in The Long, Dull Winter. She was originally voiced by Michael Caloz, but in this episode, she is voiced by Patricia Rodrigues.
Grandma Thora recalls the time during her childhood when the Graf Zeppelin flew over her neighborhood. The Graf Zeppelin was a dirigible from Germany that was first built in 1928 and used up until 1937 (as a response to the Hindenburg wreck that year). The zeppelin was famous for its flight around the world in 1929, which only took 21 days.

A Charlie Brown Christmas is referenced twice in this episode. First, the boy in "The Boy Who Got Clothes For Christmas" is dressed exactly like Charlie Brown. Second, Arthur complains about the holiday that he and his friends are creating as "already being too commercial." This is exactly the complaint Charlie Brown makes about Christmas in "A Charlie Brown Christmas."
