Zoidberg shivers while he tells Hermes that he's cold-blooded. Cold-blooded animals don't shiver.
In this episode it is revealed that global warming occured but was cancelled out by Nuclear Winter but in "A big piece of garbage" Mayor Poopenmeyer reveals that global warming was a scientific fraud.
When Leela cuts down the Xmas tree, she uses the laser and cuts it at the very bottom, but when they are taking it back on top of the space ship, it looks like they pulled the tree from its roots, not cut down
Why would Amy need to sell her hair in order to buy Hermes an Xmas present? It's been established back in Amy's very 1st appearance that she is staggeringly rich.
Opening theme promotion: BASED ON A TRUE STORY
Isn't it slightly illogical for there to be a soup kitchen for homeless robots? Wouldn't it be easier to simply dismantle them or recycle them into something else?
Response: Robots have been established as having personalities and rights (even garnering pay and having the ability to vote, so dismantling and recycling them would be controversial, and essentially akin to murdering homeless humans.
Dr. Zoidberg is portrayed as a Jesus-figure, being the only person who was judged to be 'without sin' by the Santa Claus robot.
Santa Claus was manufactured by the Friendly Robot Company, not Mom's Friendly Robot Company.
In the clock tower, there's a sign that reads "No Banana Peels."
The Preachorbot's name is Reverand Lionel Preacherbot.
Bender gets a card from his mother, which is some kind of robotic arm, but in another episode we see Bender being built in a factory, without the robotic arm.
When Fry is on the ledge trying to get the parrot, we see the city in the background, and there is no trace of snow, despite it snowing in the rest of the episode.
In the scene where Hermes is about to bobsled, the mittens on Zoidberg's claws disappear without notice.
When Leela grabs Fry after he fell from the large digital clock, she grabs his wrists with her thumbs inward and when the angle changes she's holding onto his wrist with her thumbs outward.
After Bender and the robot hobos rob the old lady's house, Bender is wearing a pink purse when they hear Fry and Leela call for help. In the next scene the purse is missing from his shoulder.
When Fry is in the pet store, his jacket is done up and he's wearing a scarf. However, after the owner shows him the electric snails, his jacket is undone and the scarf has disappeared. It is all continuous, so he would not have had time to undo the jacket and take off his scarf.
Santa: I'll be back. Back when you least expect it: Next Xmas!
Fry: The important thing is we're all together for Xmas. And even though I'm surrounded by robots and monsters and old people, I've never felt more at home.
Farnsworth: Hear, hear! Now let's all of us shut up and sing!
Fry: Look, the food isn't what's important.
Tinny Tim: I'm so hungry.
Fry: Uh, Bender? Where did you get that bird?
Bender: I found it lying in the street, like all the food I cook.
Santa: Ho, ho, ho! Time to get jolly on your naughty asses!
Leela: Watch out! His belly is shaking like a bowl full of nitro-glycerine!
Santa: As for the rest of you, I'm going to tear off your skin like wrapping paper and deck the halls with your guts.
Bender: Yeah? Well I don't believe in Santa Claus. Come on, everybody, if you don't believe in him, he can't hurt you. [Santa whacks Bender over the head with his sack.] Ow! God! The pain!
Hermes: Sweet manatee of Galilee!
Zoidberg: Amy, this is for you. A set of combs for your beautiful hair.
Amy: Oh, that's so sweet. But I sold my hair to a wigmaker so I could buy a set of combs for Hermes.
Hermes: Oh, the irony. I sold my hair so I could buy this third set of combs for Zoidberg.
Santa: Ho, ho, ho! You've been very naughty, Bender.
Bender: What? Me? I didn't do nothing. You're thinking of the kid.
Santa: My God, Bender! Framing an orphan? That's so naughty I'll have to add it to my list right now.
Leela: Somebody help us.
Tinny Tim: It's humans. Shall we mug them, robot sir?
Bender: No, wait, I know these guys. They got nothing.
Bender: On the 4th day of Xmas I stole from that lady.
Robot #1: Four family photos.
Tinny Tim: Three jars of pennies.
Robot #2: Two former husbands.
Bender: And a slipper on a shoe tree.
Fry: Please let us live! We'll put out milk and cookies for you!
Santa: You dare bribe Santa?
Fry: I just wanted to do something to make you happy. I mean, I miss my family but you never even had a family.
Leela: It's OK. You're lonely and I'm lonely. But, together, we're lonely together.
Fry: Alright, bird, you thought you could beat me in a game of wits. But you just met your equal.
Leela: Wait! You mean he's still out? His life's in danger!
Leela: I'm telling you why. Santa Claus is coming to town!
Leela: It's just that I get tired of Fry always only thinking of himself.
Hermes: I hear that! I aks him to set the table, instead he goes out to buy you a present. Selfish dog.
Leela: Sorry I stormed out before. I didn't mean to ruin everyone's Xmas.
Farnsworth: Huh? You were gone?
Salesman: Best? Well that's a matter of opinion. I personally like the Electric Snail.
Fry: That's a stupid animal. You're stupid! I said I want the best one. Now which costs more? The parrot or the Stink Lizard?
Salesman: The lizards are a buck each, the parrot is $500.
Fry: That's a hell of a good parrot. Although, I could get 500 lizards for the same price. Girls like swarms of lizards, right?
Salesman: Sir, the store is closing in two minutes.
Fry: Alright, I'll take the 500 lizards. No, wait, yes. No. Yes. Yes. Yes! The parrot!
Tinny Tim: Excuse me, sir? Might I have a sip of booze?
Preacherbot: I'm sorry, Tinny Tim. Seems we ran out early tonight.
Tinny Tim: I understand.
Bender: My God! That poor kid! Ha ha ha!
Preacherbot: Welcome, brother! May the blessings of the season be upon you.
Bender: Yeah, yeah, amen. Listen, I'm one of those lazy homeless bums I've been hearing about. Could you point me to the free booze?
Farnsworth: Back in 2801, the Friendly Robot Company built a robotic Santa to determine who'd be naughty and who'd been nice and distribute presents accordingly. But something went wrong.
Fry: Wow! 2801! Anyway...
Farnsworth: Wait, you fool! Due to a programming error, Santa's standards were set too high and he invariably judges everyone to be naughty.
Amy: If he catches you after dark, he'll chop off your head and stuff your neck full of toys from his sack of horrors.
Farnsworth: Nice meeting you.
Amy: Where are you going, Bender?
Bender: To volunteer at a liquor kitchen for homeless robots.
Hermes: Yeah, right! As if you ever did anything charitable.
Bender: I'm very generous. What about that time I gave blood?
Fry: Whose blood?
Bender: Some guy's.
Bender: Xmas Eve; another pointless day where I accomplish nothing.
Linda: The holiday season is a time of celebration for most. But it is also a time to remember the tragic suffering of the less fortunate.
Morbo: Earthlings do not yet know the meaning of suffering.
Farnsworth: You should be ashamed of yourself, Fry. You'd have to be blind not to notice that Leela's a cyclops.
Hermes: Fry's over there, man.
Fry: I feel like a rat. Here I am whining like a pig while all along Leela was lonely as a frog. I could kick myself.
Amy: I'll do it for you. (kicks Fry)
Fry: Ow! Thanks.
Fry: This dumb holiday just makes me think of all the things I left behind. Let's just stop talking about Xmas.
Hermes: Happy Xmas, Xmas people! Xmas cards have arrived! Xmas! Amy, there you go. Fry, Professor, Zoidberg, a mighty haul for Bender.
Bender: Yes! I got the most! I win Xmas!
Fry: Every Christmas my mom would get a fresh goose for goose burgers and my dad would whip up his special eggnog out of bourbon and ice cubes.
Fry: They're supposed to be some kinda, you know, pine tree.
Farnsworth: Pine trees have been extinct for 800 years, Fry. Gone the way of the poodle and your primitive notions of modesty.
Bender: Ah! Nothing like a warm fire and a Super Soaker of fine cognac.
Fry: Yeah, it really puts you in the Christmas spirit.
Fry: Christmas. You know? X-M-A-S.
Leela: Oh, you mean Xmas. You must be using an archaic pronunciation. Like when you say "ask" instead of "aks".
Zoidberg: You, a bobsledder? That I'd like to see!
Hermes: Listen, you filthy crab, a thousand years ago there was a legendary team of Jamaican bobsledders.
Fry: Yup, I remember. They came in last at the Olympics then retired to promote alcoholic beverages.
Hermes: A true inspiration for the children.
Man #1: Excuse me, sir, you're snowboarding off the trail.
Bender: Lick my frozen, metal ass.
Hermes: Sweet lion of Zion!
Hermes: Jah damnit! We're stuck.
Zoidberg: At least you're not cold-blooded!
Fry: This snow is beautiful. I'm glad global warming never happened.
Leela: Actually it did. But thank God nuclear winter cancelled it out.
Farnsworth: Come on, everyone. Perhaps some skiing will help us forget the mouldy old antics of Conan O'Brien.
Leela: Great idea!
Zoidberg: We can only hope!
Bender: Ah, lets face it: Comedy's a dead art form. Now, tragedy... That's funny!
O'Brien: So, people are getting pretty worried about this Y2K problem, huh?
Bender: No, they fixed that 900 years ago.
O'Brien: Just bear with me, sir. Anyway, I'm walking to work this morning-
Bender: I doubt it!
O'Brien: Listen, pal, I may have lost my freakishly long legs in the war of 2012 but I've still got something you'll never have: A soul!
O'Brien: And freckles!
"He knows when you are sleeping
He knows when you're on the can
If he sees you he'll blast your ass from here to Pakistan!
Oh, you better not breathe
You better not move
You're better off dead I'm telling you dude
Santa Claus is gunning you down!"
Fry: I never thought it would end this way: Gunned down by Santa Claus. Honestly, I didn't see it coming!
Linda (the newscaster): Homeless robots, to poor to even afford the basic alcohol needed to fuel their circuits. Is there anything sadder? Only drowning puppies, and it would have to be a lot of them.
Fry: There's this girl who I really like, but she thinks I'm a jerk. Can you help me?
Man: Yeah, there's a suicide booth in the food court. Though there's a line this time of year.
Santa: I'm gonna shove coal so far up your stocking you'll be coughing up diamonds!
Santa: Your mistletoe is no match to my Tow missile!
Leela: We set things right! Fry even risked his life to buy me a present!
Santa: But what about your other coworkers? Did either of you ever stop to think about Dr. Zoidberg's feelings?
Fry: No! I swear!
Farnsworth: They'll be killed on our doorstep, and there's no trash pickup until January 3rd!
Santa: You all been naughty! Very naughty indeed! Except you Dr. Zoidberg. This is for you.
Dr. Zoidberg: A Pogo Stick!
First appearance of Robot Santa.
The idea that an artificial being can't tell the difference between true naughtiness and just being children (i.e. wiping boogers on another person's shirt) is also used in the movie The Santa Clause 2 by the toy Santa.
Alien code: While Fry is admiring the bird he has bought for Leela, he passes by a sign written in Alien Code #1. When translated it reads "Joyeux Noex," or for which in French means "Merry Xmas."
There is also a sign in Spanish that reads "Cerrado para Xavidad (Closed for Christmas/Navidad)."
Alien code: When bringing a tree back for Xmas, the ship passes by a sign that says Human Power, but has Alien Code #1 below it. The code reads "Disposable Office Temps"
This episode was rerun especially on 25 Dec 99. The same thing happens with this year's Simpsons Christmas episode. Then Futurama moved to a new time slot (7:00pm EST/PST) which cause a little bit of stir with series creator Matt Groening.
Hermes: Listen, you filthy crab, a thousand years ago there was a legendary team of Jamaican bobsledders.
Reference to the Jamaican Bobsled Team, which debuted on the 1988 Winter Olympic Games. The movie Cool Runnings (1993) is loosely based on their story.
Conan O'Brien mentions a war having occured in the year 2012. This is in reference to the many theories and prophecies of catastrophe associated with that particular year.
When Fry is looking for a pet, there is a creature resembling a bunny with one ear. This creature is named Bongo and comes from Matt Groening's Life in Hell comic books.
Fry: Ah-hah! Cornered!
Fry hanging from the clock tower must be a tribute to the classic movie Safety Last featuring Harold Lloyd.
Santa Claus Is Coming To Town
The last number of the show is a take on the holiday classic "Santa Claus Is Coming To Town."
A Charlie Brown Christmas
The skating children scene is a take right from the show. The background music is a take off the show's Christmas theme.
Late Night with Conan O'Brien
A former writer for the Simpsons, with his self-deprecating humor, his band is led by Max Weinberg.
The Gift of the Magi: by O. Henry
Amy and Hermes both got combs for their hair which they sold to buy combs for each other (and Zoidberg). In the Gift of the Magi, a woman sells her hair to buy a chain for her husband's pocket watch, which he had already sold to buy her a set of combs.
Tinny Tim: Please sir, may I have some more?
This quote is a reference to the Charles Dickens book "Oliver Twist", in which the title character says the same line. Also, the robot's name is a reference to Tiny Tim, a character in "A Christmas Carol".
A Christmas Story
The title is a reference to the movie, A Christmas Story.
