C'mon, you have to admit that this movie made you giggle at some points.
- "Grandpa's Gonna Sue the Pants Off of Santa" is sort of hilarious in a way, with I.M. Slime's deadpan voice in the background spouting out random Spanish and Latin lines such as "No pantalones!" and "Vamanos!".
- Also, because Mel and Slime are doing the samba with fruit baskets on their heads with Hawaiian/Brazilian music in the background, singing with voices that sound like roosters screaming.
- "Your share as Grandpa's financial advisor is.....'woof'." "WOOF?!?!"
- The way "Grandma's Spendin' Christmas with the Superstars" gets started:Mel: It's right in these papers, all you have to do is sign.Grandpa: Sing?Mel: No, sign.Grandpa: Sure!Mel: So SIGN!Grandpa: I'd rather sing!
- The whole special—if not for the cheesy Plot Holes, how Narmy everyone acts, and the shoehorned fruitcake 'jokes'. It's pure unadulterated Narm Charm; most people would be lying if they said they didn't enjoy the hell out of this show.
- "I'm Grandma! And I'm not missing! I'm right here."
- "That woman is a fraud! Grandma doesn't know who she is!" Cue massive Face Palm from I.M. Slime.
- As Cousin Mel is admitting to everything she'd done in court, the way she offhandedly states "I'm behind this evil trial" is hilarious.
- Grandma getting run over again.
- I.M. Slime introducing herself and Jake's reaction (along with an out-of-nowhere beat).IM Slime: Mel's attorney, I.M. Slime.Jake: You said it, not me.(cue Beat)
- Narrator Jake's line about fruit cake.Jake: The way I see it, you can divide the world up into two groups: people who like fruit cake, and all the rest of us!
- And in the resulting sequence, the shot for "one's enough to give the whole state of Kentucky a great big bellyache" is of Kentucky burping.
- Grandma got run over by a reindeer, all right. And as incredible as that was, it almost put an end to Christmas.
- This quote:Mel: "Since Grandma is nowhere to be found, and the man in the red suit admitted he ran over her, I demand you have Santa arrested for the disappearance of Grandma!"
- The fact that, for some weird reason, they decided to name the main family "Spankenheimer".
- How embarrassed the reindeer Jake brings in for demonstration purposes is about going hog wild over the reindeer nip-spiked cake in the courtroom.Reindeer: (sheepishly) I couldn't control myself...
- One of the few unironically funny tidbits in the film is when Cousin Mel is gloating about how no one can stop her Evil Plan when someone (Quincy disguised as a forest ranger) knocks on the cabin door. When Mel wonders who that could be, Grandma bluntly responds "How should I know? I don't even know who I am." Susan Blu's deadpan delivery of the line is what makes it so hilarious.
- When everyone dresses in black after Grandma's disappearance, Daphne uses it as an excuse to have a goth phase.
