|It's almost winter break as the students at Greendale prepare for their final exams of the semester. In the cafeteria, Shirley hands out presents to the rest of study group. She made them all bracelets with the letters WWBJD which she explains is short for "What would baby Jesus do?". Elsewhere in the cafeteria, Abed is grabbing free cookies for the group when he is accosted by another student for taking the last of the winter doodles. After he shoves Abed, Jeff steps in to defend him. His snarky attitude does little to defuse the situation and instead ends up making the other student angrier. The arrival of the Dean dressed as "Mister Winter" puts an end to the confrontation temporarily, but the student warns Jeff that this isn't over.
|Later in the study room, Abed excitedly tells everyone how Jeff stood up for him in the cafeteria. Pierce wonders why Jeff didn't fight the guy while Shirley says she's proud of Jeff for turning the other cheek. Pierce argues that fighting is something men need to do. Britta counters that it's just a way for them to relieve their pent-up gayness. Jeff tries to get everyone back to studying for the finals as he is going to fail unless he passes the last exam. Shirley interrupts and asks when everyone is coming to her Christmas party. She then discovers that each of them have different faiths. Annie is Jewish, Abed is Muslim, Troy is a Jehovah's Witness, Britta's an atheist, Jeff is agnostic, and Pierce is a born again Buddhist. Despite her initial concerns, she decides to open the party to all faiths.
|Mike & Co. burst in on the Spanish exam to harass Jeff who is finally fed up enough to challenge Mike to fight. While discussing the pending confrontation with the guys Jeff reveals he has never been in a fight so the others agree to coach him. When she hears about the fight, Shirley interrupts their training session to plead with Jeff not to fight saying that he can't attend her Christmas party if he fights Mike.
At Shirley's party, she tries to welcome everyone but has difficulty concealing her discomfort with the others' beliefs. As tempers begin to flare Shirley proclaims that she wants her new family, the study group, to be together because her old family is falling apart due to her husband's unfaithfulness. Britta points out that Shirley needs to accept everyone, faults and all, if she wants to grow close. With that, everyone leaves to watch Jeff's fight.
In the quad, Jeff approaches Mike but realizes that Shirley's friendship is more important than his own pride and refuses to fight. Shirley watches as Jeff stands down only to be sucker punched by Mike. She quickly joins the fray with the rest of the study group. Later, the party is continued and Shirley sings modified and non-denominational lyrics to Silent Night as we see everyone bloodied and bandaged from the fight. Señor Chang walks in announcing everyone passed the exam and Jeff toasts everyone to the upcoming semester.
Abed sings O Christmas Troy while piling decorations on Troy when Jeff walk in and asks why they do this kind of thing. Troy replies that it's fun so Jeff joins in the festivities.
- First appearance: Mike is introduced in this episode. He later has a cameo in the Season Two episode A Fistful of Paintballs. Pierce's religion, Reformed Neo Buddhism, makes it's debut.
- Familiar face: The Greendale Human Being returns dressed as a reindeer and pulling Mr. Winter's sleigh with a bike.
- Mad skillz: Shirley sings a lot in this episode and Pierce accompanies her on the keyboard for one of those songs.
- This must be the place: Group Study Room F, the administrations office, the cafeteria, the spanish classroom, the storage room, and the campus quad in front of the library are all featured prominently in this episode.
- Special Drink: In the end rag Troy mentions Abed's 'special drink' which Abed refers to in the first episode and is just hot chocolate served cold.
- Attention students!: Dean Pelton makes an announcement about winter break, the Winter Wonderland display in the quad which has catalogs for next semester's classes, and the appearance of "Mr. Winter" later in the student lounge.
- Nice outfit: Dean dresses up as "Mr. Winter", the non-denominational representation of Christmas.
- Double entendre: Shirley says she is tired of the Dean shoving his P.C.ness (political correctness) down her throat. Troy and Pierce eventually notice that P.C. sounds like penis but miss the more obvious fellatio parallel.
- WWBJD?: Shirley hands out bracelets inscribed with the acronym and is upset when she finds out that the study group follow different faiths from hers. She also pleads with Jeff not to fight Mike and instead turn the other cheek in keeping with her beliefs.
- Gay, he's so gay!: Britta teases Jeff about the homosexual undertones in the fight he has with Mike.
- NOOOOOO!: Annie screams this when she thinks Chang is about to tell Jeff that he failed Spanish 101.
- Use your allusion: Shirley's bracelets are an allusion to the popular 1990's phrase "What would Jesus do?" that was used to promote Christian values. The phrase was merchandised and sold in various forms, particularly bracelets.
- Résumé: Mike is played by Anthony Michael Hall who starred with Chevy Chase in the 1983 comedy National Lampoon's Vacation. Pierce says he knows guys like Mike who "used to be nerds and now are meatheads". This is referencing Hall's transition from nerdy, wimpy roles in teenage movies like the The Breakfast Club to the more mature and antagonistic roles he later had such as the bully in Edward Scissorhands.
- IRL: The religions Annie, Troy, Abed and Shirley practice all correspond to the religions of their respective actors: Alison Brie is Jewish, Donald Glover was once a practicing Jehovah's Witness, Danny Pudi is Muslim, and Yvette Nicole Brown is Christian.
