- Hello?

- Roger? Did I wake you?

- Yeah.

- Oh, sorry. Listen. I've got something down here I'd like for you to look at.

- What?

- I know I could be wrong, but I don't think it's a car part at all. Maybe you've seen something like it.

- How's tomorrow afternoon?

- Tomorrow afternoon? Okay, great. Thanks, Roger.

- Bye.

- Operator, can you get me the sheriff...?

- Enjoy the Horrorathon, Doctor. And don't forget to watch the big giveaway afterwards.

- Why, Cochran? Why?

- Do I need a reason?

- Mr. Kupfer was right, you know. I do love a good joke. And this is the best ever. A joke on the children.
