Although it was the first to air, it was technically supposed to be the eighth episode; the first episode production-wise was intended to be “Some Enchanted Evening”, but due to animation problems from South Korea that resulted in “Some Enchanted Evening” to be postponed until the season finale, this episode ended up being first.

Bart yanks Homer's beard off in the mall, and Homer then takes Bart into Santa's workshop. When they are inside Santa's workshop, Homer's beard is back on, despite the fact that he didn't put it back on; he let it fall to the ground when Bart pulled it off.
When Marge is talking on the phone to Patty and Selma, they mention something that sounds like they said that Homer is ugly. Marge then puts down the phone wire that she was curling around her finger. It is easier to see this when you are using DVD, because then you can go into slow-motion, but you can temporarily see that the phone wire disappears when Marge puts it down. It is at the very end of an early scene, because as soon as this happens it changes to another scene.
When Homer finds out that he has no Christmas bonus, the background behind Marge is the kitchen, but then it cuts to Homer and the background behind him is the kitchen, too.
When Homer has been informed about the Christmas money being spent on Bart getting his tattoo surgically removed, he leaves the house. When he opens and closes the door to leave, the wreath on the door is white with a red bow. When Homer then turns to look his Christmas decorations, the wreath is now green.
Just before the kitchen mistake, Marge comes through the door and you see that she has come from a room with a piano in it. It has a musical book on it, but when the shot changes so we see Marge turn the jar upside down, the book of musical notes has disappeared.

When Milhouse, Bart and Lewis are talking about the fake Santa, Milhouse's eyebrows go from blue to black to blue again.
When Homer walks up the front drive you can see the road and there are no markings on it, but when he turns to look at his house, there are orange lines running down the road.
If Barney were really Homer's friend, he would have shared his money.
After Homer brings Santa's Little Helper home, Homer and Marge hug, and if you look behind them, the background is upside down. There is a picture hanging upside down, and there is a lamp which seems to be hanging from the ceiling. Then in the next shot, the background is normal.

Goldfinger: Bart is strapped to a table with a laser beam moving towards him.
Gift of the Magi: Homer doesn't get his Christmas bonus and says to himself, "Oh, well, thank goodness for the big jar." Marge used her money to remove Bart's tattoo and says to herself, "Oh, well, thank goodness for Homer's Christmas bonus." This was similar to how in this short story by O. Henry, a man sells his watch to buy his wife an expensive set of combs and his wife has her hair cut, selling the remainder to a wigmaker, in order to buy a gold chain for her husband's watch.
The title of this episode is a reference to “The Christmas song”, also known as “Chestnuts Roasting on an Open Fire”.
