YMMV: The Simpsons S 10 E 4 Treehouse Of Horror IX
- Crosses the Line Twice: When Snake's hair latches onto Bart's face, Homer starts punching Bart's face.
- Nightmare Fuel: During "The Terror of Tiny Toon", Bart is reduced to a skeleton by a stream of piranha coming out of a fire hose.
- One-Scene Wonder: Krusty appearing in vampire getup to host the Itchy and Scratchy segment of "The Terror of Tiny Toon". Reached Ensemble Darkhorse status considering how that incarnation of Krusty became a Burger King Halloween toy and appeared in some Treehouse of Horror merchandise and imagery, despite not really playing a role in the segment.
- Ugly Cute: Maggie when she transforms into an alien.
- We're Still Relevant, Dammit: The "Don't forget Ken Starr!" line was clearly added during post-production and given the recency of the event in question, it was likely an attempt at this trope, though not as blatant as the trope would be in later episodes.
