In 1998's tales of terror, Homer gets a hair transplant from a dead criminal (Snake Jailbird), Bart and Lisa go on TV (thanks to a radioactive remote control), and The Simpsons are the latest guests on The Jerry Springer Show after Marge confesses that Maggie was the product of an abduction-cum-one night stand with Kang the alien.
This episode contains examples of: (YMMV Examples here)
- Angry Fist-Shake: Snake's hair after being shot several times.
- Animated Actors: Hinted to be the case with Itchy and Scratchy during "The Terror of Tiny Toon".
- Arson, Murder, and Jaywalking: The three strikes Snake was executed for were: setting fire at an orphanage; blowing up a busful of nuns (which Snake declares was in self-defense); and smoking at a Kwik-E-Mart.

- Darker and Edgier: The episode uses a more macabre version of the show's opening sequence. We have Bart writing down the chalkboard punishment in blood, later him botching his jump off Homer's sunroof and snapping his neck. Lisa then follows suit by cycling into Bart's corpse and ricocheting headfirst into the garage wall, as Homer gets run over by Marge as she drives by. The couch gag then sees Freddy Krueger and Jason Voorhees sitting on the couch, apparently waiting for the family to arrive.
- Disproportionate Retribution: Because one audience member called out Kang for being a deadbeat father, he kills the entire Jerry Springer audience.

Homer: But I love my son.
Snake: More than a lush head of hair?
Homer: Don't make me choose!
(Snake does an Evil Laugh.)
Homer: NO! (Proceeds to literally Drop the Hammer from his hands and tear Snake's hair off his head.)
- For Halloween, I Am Going as Myself: Marge asks Homer if he dressed up as a hobo again for Halloween but he actually had no intention to do so and was just unkempt as usual.
- Gory Discretion Shot: During Apu's murder.

- Medium Blending: In "The Terror of Tiny Toon", Bart, Lisa, Itchy and Scratchy fall into the live action "Live With Regis & Kathie Lee" (as it was then titled) show. Regis Philbin and Kathie Lee Gifford both appear as themselves.
- It took so long to get the live-action part right, they couldn't broadcast the news from the same studio (Live began as a local morning show on New York's ABC station, and it's been taped there, so they had to share studio space with Eyewitness News, which moved to a street-side studio in 2010).
