* "Real estate!"
** Ruined in the Polish translation, which translated this line simply as [[BlindIdiotTranslation "Something valuable!"]].
** The original Finnish dub misses the joke completely: Lucy says that she wants ''reality'' for Christmas.
* Schroeder trying to play ''Jingle Bells'' to Lucy's satisfaction.
** Not to mention him playing an extremely simple version with a glare on his face, then having Lucy scream "THAT'S IT!!!", sending him flying.
** His first attempt has his piano sounding like a regular grand piano, his second attempt has it sounding like an ''organ'', and his exasperated attempt actually sounds like a toy piano.
* Snoopy mocking Lucy's directing demands and gestures, then ducking her fist and [[TakeThatKiss licking her]] in retaliation.
** '''Lucy''': "Yes, he's even a good [[EverythingsBetterWithPenguins penguin]]."
** Better yet, Snoopy does an imitation of all the animals Lucy wants him to do and after she says the above-mentioned line, he jumps onto her head, imitating a vulture. To this day, whenever my family and I see an animal or someone doing the vulture imitation, we immediately say, "Vulture eyes."
* Linus gets a lot of good lines:
-->"Christmas is not only getting too commercial, it's getting too dangerous."\\
"Gee, [[RealityIsUnrealistic do they still make wooden Christmas trees]]?"\\
"You know, maybe Lucy's right -- of all the Charlie Browns in the world, you're the Charlie Browniest."
* '''Charlie Brown''': "I've killed it..."
* The kids dancing, particularly Shermy doing the zombie walk and 5 doing...whatever he's doing.
** And Violet's air-punching. What's up with that?
* This Exchange:
-->''(Lucy & Linus are arguing over Linus having to memorize a script)''
-->'''LINUS:''' "Just give me one good reason why I should go through such agony!"
-->'''LUCY:''' "I'll give you ''FIVE'' good reasons!" *''holds up five fingers and makes, finger by finger, into a fist''* "One! Two! Three! Four! ''FIVE!!'' "
-->'''LINUS:''' "''Those are good reasons!'' Christmas is not only getting too commercial, it's getting ''too dangerous!''"
