- Lisa Simpson: If Scooby Doo has taught me anything, it's that there's nothing to be afraid of except crooked real estate developers.
- Marge: What ever happened to 'please' and 'thank you'?
- Homer Simpson: They killed each other. Ya know, one of those murder-suicide deals.
- [Lisa looks out the window to see man resembling Groundskeeper Willie digging a grave]
- Lisa Simpson: Groundskeeper Willie?
- Gravedigger Billy: No, I'm his cousin, Gravedigger Billy. I've been digging graves for 30 years and I've never buried anyone alive. If I did, they'd be ringing this bell.
- [the bell rings]
- Gravedigger Billy: Oh, that's just the wind.
- [a hand emerges from the grave]
- Gravedigger Billy: Oh, that's just a tree branch, with a nice watch on it.
- [Billy grabs the watch and starts hitting the hand repeatedly]
- Lisa Simpson: Dr. Nick? What are you doing here?
- Dr. Nick: I'm not Dr. Nick!
- [puts dead people's arms around him]
- Dr. Nick: I'm Dr. Octopus! "I'm gonna get you, Spidey!"
