Homer becomes the new Grim Reaper (not unlike the Family Guy episode that did the same story), Professor Frink is a Mad Scientist trying to build a corporeal body for the spirit of his dead father (played by none other than the inspiration for Professor Frink's character, Jerry Lewis), and Bart and Milhouse buy a stopwatch that manipulates time.
- And This Is For...: When Homer killed the Grim Reaper, he said it was for Snowball and Kennedy.
- Be Careful What You Wish For: At the end of the final segment, when Lisa realises what Bart has been doing with the stopwatch, she asks, "Why can't I tinker with the fabric of existence?" Homer has Bart give her the stopwatch, and she notices a red button on it. She presses it to see what it does, only for the rest of the family's bodies to split into rockets. She ends up changing them multiple times, trying to correct her error.
- Big "NO!": Homer's reaction upon the idea of a world without death meaning Jim Belushi would never be cancelled.
- The Bus Came Back: The "Scary Names" for the credits return after being absent for 2 Halloween specials. Al Jean's "Scary Name" credit lampshaded this.
- Fanservice: A female crossing guard in Sweden is depicted working completely naked for no reason.
- God: He tries and ultimately fails at chasing Homer, only for him to give up and to admit that he's "too old and too rich for this."
- Groin Attack: That was how the Grim Reaper's robe forced Homer to take on the job.
- Ditto on how Frink kills his re-animated father.
- Laser-Guided Karma: Happened instantaneously to Nelson, who Bart and Milhouse bring into the scene to laugh at a naked Homer, only for his clothes to disappear before he can finish his Signature Laugh.
- Rule 63: Briefly happens to Homer, Marge, Bart, and Maggie◊ when Lisa keeps messing with the watch at the end. On the upside, this is the first change that restores Bart to his original age.
- Scooby-Dooby Doors: As Death tries to take Bart, he gives him chase, setting up a hilarious game of this, complete with "Yakety Sax" to top off the scene.
- Suicide as Comedy: After realizing all of the doughnuts in the break room keep disappearing before he gets a chance to eat them, Homer decides to stab himself in the stomach...only for the boys to replace the knife with a banana at the last second.
- Take That: The aforementioned Big "NO!" example regarding Jim Belushi.
- What Does This Button Do?: When Lisa gets the stopwatch, she gets curious over its red button. She ends up repeatedly changing the other Simpsons with each press of the button.
