* The first lines of the cartoon, as Lucy's carving the pumpkin:
-->'''Linus:''' *anguished* "Oh! You didn't tell me you were gonna kill it! AWH!"
* Lucy's advice on choosing the perfect Halloween costume before donning her witch costume:
-->'''Lucy:''' [[HypocriticalHumor "A person should always choose a costume that is in direct contrast to her own personality."]]
* Sally getting scared by her own bed sheet ghost costume.
* Charlie Brown's BedsheetGhost costume with a surplus of eyeholes. [[EpicFail It takes effort to botch something so simple that badly]], and is all the funnier for it. "I had a little trouble with the scissors."
* After Linus tells Sally about the Great Pumpkin:
-->'''Sally:''' [[SarcasmMode That's a good story.]]
-->'''Linus:'''You don't believe the story of the Great Pumpkin? I thought little girls always believed everything that was told to them. I thought little girls were innocent and trusting.
-->'''Sally:''' Welcome to the 20th century.
* When Lucy uses her sweetest voice to ask an adult for some candy she can give to "[her] stupid brother".
* When Lucy goes bobbing for apples and comes up with one that has Snoopy on the other side and freaks out.
-->Blecch! My lips touched dog-lips!
* When Schroeder plays "It's a Long Way to Tipperary", "There's a Long Long Trail" and "Pack Up Your Troubles" in succession, and Snoopy's responding mood shifts from happy to sad accordingly...
** Culminating when Schroeder's rendition of "Roses of Picardy" provokes an "[=OwwwOOOOOOOoooooooOOOOhhhhhhhhh!=]" from Snoopy.
* Snoopy rising out of the pumpkin patch and causing Linus to faint; then disappearing immediately after.
* When the Great Pumpkin fails to appear, Sally gives Linus an epic dressing-down that culminates in her violently shaking him while hollering "YOU OWE ME RESTITUTION!"
* Charlie Brown trying to console Linus:
--> Well, don't take it too hard, Linus. I've done a lot of stupid things in my life, too!
** He had inadvertently pushed Linus' BerserkButton when he said that. Linus proceeds to berate him all through the credits.
* Charlie Brown being forced to be a model.
** ...for a jack-o-lantern.
* A brief visual gag with Lucy holding a copy of TVGuide with ''her own picture'' on it.
* When Snoopy first sees Linus writing to the Great Pumpkin, the beagle starts laughing hysterically. He walks over to Lucy while laughing...who promptly tosses him away like a rag doll.
* In the beginning, Linus, eating a huge sucker & is sticky as all get out, jumps in Charlie Brown's leaf pile & ends up with a leaf-covered confection & an adorkable "beard" of leaves. Quoth the leaf-bearded Van Pelt boy, "Never jump into a leaf pile with a wet sucker!"
