Psych-Out: We get an alternate ending to the episode in which Mr. and Mrs. Guster confide in Shawn that they really did murder the old man.
Pineapple Watch: While Henry is taking food containers out of the refrigerator, Shawn grabs the pineapple that's sitting by the containers.
This episode featured special Christmas-themed opening credits, complete with falling snow, Christmas lights, and bells.
It's quite appropriate that Shawn gave Henry a snow globe for Christmas—Corbin Bernsen, who plays Henry, is actually an avid collector of snow globes and estimates that he owns at least 7,000 of them.
(McNab leaves with his BB gun Christmas present)
Gus: He's gonna shoot his eye out.
Shawn: Yes, he is.
Shawn: Lassie! (hands Lassiter a snow globe)
Lassiter: I-I hate snow globes.
Shawn: Ah, that's strange. My psychic senses told me specifically that snow globes didn't give you nightmares about being trapped in a clear ball with snow that burns your skin off.
Shawn: (to Juliet) I can think of someone who could use a little cheer this time of year. Recently divorced...
Gus: (correcting Shawn) Separated.
Shawn: And all alone for the holidays...
(they look over at Lassiter, who groans at the sight of numerous snow globes on his desk)
Lassiter: All right! Who keeps telling people I want snow globes for Christmas?
Shawn: (to Gus) In over twenty years of friendship, I can count on one shop teacher's hand the number of times your folks have had us over.
(Shawn wonders why Gus' parents don't invite him over more often)
Gus: Let's just say it's not because of your dad.
Shawn: (laughs) What, your house is too small? Didn't have enough extra chairs?
Shawn: Hiding a Jewish family in your attic?
Gus: My parents always thought you were a bad influence on me. Understandably.
Shawn: A bad influence?
Shawn: Dude, that's absurd.
Gus: Because of you, Shawn, I got my first "B," broke my first curfew, accidentally killed the state bird...
Shawn: How was I supposed to know he couldn't hold his own liquor?
Shawn: You know why Gus isn't a smoker? 'Cause when we were kids, I made him smoke an entire pack of cigarettes, and he discovered he hated the taste. Pretty good influence if I do say so myself.
Winnie: Probably what gave him asthma.
Bill: Probably what stunted his growth, too.
Gus: (defensively) I'm five-ten-and-a-half.
Shawn: (to Gus' parents) And I'm the one that let Gus believe that Jesus was black, the whole time we were gro-growing up—which, of course, he is. He is that. That's—he is that.
Shawn: Whoa, whoa, whoa, stop! I'm sensing something.
Gus: What is it, Shawn? Is it like the other twenty-six and a half crimes we solved for the police department?
(Shawn says the death was murder, not suicide)
McNab: According to CSU, Shawn might be right.
Shawn: Colorado State University?
Gus: Crime Scene Unit.
Shawn: Them, too.
Lassiter: (to Juliet's nephews) Let's do one with Santa in it. Hand me Kris Kringle there, guys.
Juliet: That's a great idea!
Lassiter: You know, interestingly enough, the Dutch version of Santa used slaves to deliver the toys.
Shawn: My God. We went almost three hours without having an argument.
Henry: Hm. It's our best holiday in years, huh?
(Henry phones Shawn to guess what his Christmas present is)
Shawn: Dad. No, it is not an engraved set of rubber bullets. Why would I possibly give you another excuse to shoot a gun?
Bill: (to Gus) This is our worst nightmare. It seems like everything is conspiring against us. So we lawyered up. That's how they say it in the bucket, son, where I did an eight-hour bid.
Winnie: I don't know those words. (starts to cry) I'm not gonna do well in prison.
Bill: Oh, don't worry, sweetheart. You'll be fine. (softly to Gus) She's not gonna make it.
Gus: (to his parents) I'm twenty-nine years old! And by the way, I know you've only been married for twenty-eight years. I did the math a long time ago, so stop protecting me from that.
Photo Guy: I remember my dad had a female friend who would visit only at night.
Shawn: Uh-huh, what was her name?
Photo Guy: I don't remember.
Gus: Do you know where she lives?
Photo Guy: No.
Shawn: Can you tell us anything? I just swung from a tree!
Shawn: Dude! Can the super-smeller pick out a scent from memory?
Gus: Well, the olfactory and memory areas of the cerebral cortex share the same neural pathways.
Shawn: What is that? Is that a yes?
(Gus accidentally bids at the auction)
Auctioneer: Sold! To the man in the blue argyle sweater for five hundred dollars, this antique Confederate battle flag! Thank you for bidding, sir. Enjoy your flag.
Shawn: (to Gus) Wow. You can totally get a gun rack for your truck now.
Shawn: (to Gladys) And then you used that chairlift to pull old man Fuller all the way up and over the banister at this ridiculous agonizing pace! And that is how you killed that ancient pruney relic!
(McNab leaves with the BB gun Shawn and Gus have given him for Christmas)
Gus: He's gonna shoot his eye out.
This is a reference to the classic movie A Christmas Story. In the film, all Ralphie wants for Christmas is an official Red Ryder carbine action two-hundred shot range model air rifle, but everyone warns him that he'll "shoot his eye out."
Shawn: I feel like Pepé Le Pew when he looked up "pew" in the dictionary. (imitates him) "Le Pew? Moi? No..."
Pepé Le Pew is a character from Looney Tunes. He is a skunk who seeks the affection of a black cat that he mistakes for a female skunk. However, the cat does not reciprocate his feelings due to Pepé's foul odor.
(Gus steps on a floorboard, making it creak)
Shawn: Dude, there's something in there.
Gus: What do you think it is?
(Shawn shakes his head and continually makes sounds like a heartbeat)
Gus: Will you stop it, Shawn. You know how that story gives me the creeps.
Gus is referring to the short story The Tell-Tale Heart, by Edgar Allen Poe. In the story, a man murders the old man with whom he lives, cuts him up, and buries him beneath the floorboards. The guilt eventually makes the man think he hears his victim's heart still beating, and, driven mad by this, confesses to the crime.
(Gus gets behind a creaky rocking chair and rocks it)
Gus: (in an elderly voice) Norman! Norman! Norman!
Gus is imitating Norman Bates' "mother" from Alfred Hitchcock's film Psycho. In the movie, a young woman at a motel is killed by what appears to be a woman. It's later revealed that the killer was Norman Bates, the motel owner, dressed up like his mother, whom he killed many years earlier. The guilt from his mother's murder manifested itself into a separate personality—that of his mother.
Shawn: (to Gus) If she's like most old ladies, she probably thinks you were on The Jeffersons, and she wears the same perfume from her youth.
The Jeffersons was a long-running sitcom that premiered in the '70s. It focused on an upper middle-class black couple, George and Louise Jefferson.
Shawn: (to Gladys) You found yourself a nice piece of rope. You tied one end around his neck, you draped the other end over the banister, and you tied it to the chairlift.
The inclusion of a chairlift is possibly a reference to the 1984 movie Gremlins, which takes place at Christmastime. While trying to get away from the little monsters, an old lady sits in her chairlift to go upstairs. Unfortunately, the Gremlins rigged her chair to ascend much faster. Upon reaching the top of the stairs, the chair flies out the window, taking the old lady with it.
Shawn: (to Henry) Oh, somebody doesn't like to lose because you're an old Grinch during Christmas time. Your name's Ebenezer Grinch-man.
Shawn first refers to the Grinch, a character from the Dr. Seuss children's book How the Grinch Stole Christmas! In the story, everyone in town loves Christmas a lot, but the Grinch does not, so he plots to stop the holiday from coming.
Shawn also references Ebenezer Scrooge, a character from the Charles Dickens classic A Christmas Carol. Scrooge is an old miser who hates Christmas, though he's generally bitter anyway, regardless of the season.
