As the Griffins prepare for Christmas by decorating their tree, Meg finds an ornament of the manger and Peter tells the story of Christmas.
Jesus Mary, and Joseph contain examples of: (YMMV goes here)
- Aerith and Bob: Amid all the biblical characters, Brian's character is named Robby. Chris lampshades this.
- Arbitrary Skepticism: Brian calls the Nativity story fictional, despite having actually met Jesus. Stewie lampshades this.
- Butt-Monkey: Meg, as usual.
- Christmas Episode: The wraparounds are fittingly set during Christmas Eve.
- Continuity Nod: When Brian calls the Nativity story fictional, Stewie replies that Jesus once lived with them for a month (as seen on "I Dream of Jesus").
- Dirty Coward: When Jesus begins killing the soldiers, Herod says he forgot something back at the castle and leaves.
- Fridge Logic: In-universe, where Mary's virgin birth makes sense when she explains it to Joseph but when he explains it to his friends they keep "poking holes" on it.
- Hypocritical Humor: After finishing the story, Lois reflects on how wonderful it is when people come together. Then a married couple about to have a baby knocks on the door and asks to use the phone. Peter accuses them of running a scam and tells them to go away, which Lois fully supports.
- Mix-and-Match Critters: A cutaway shows Peter's last Christmas gift to Lois: two turtle/dove hybrids.
- No Sympathy: The Griffins to the out of town couple in need of a phone.
- Take That!: The trailer for the Ben-Hur version of Jack and Jill.
- Talking Animal: Meg as the donkey.
- Would Hurt a Child: Herod (played by Carter) intends to kill Joseph and Mary's baby.
- Yet Another Christmas Carol: During a break in the story, the Griffins watch a version where the Ghosts have to wait for Scrooge to finish up in the bathroom.
