Hoggle: You need to understand my position: I’m a coward. And Jareth scares me.
Sarah: What kind of position is that?
Hoggle: No position! That’s my point. And you wouldn’t be so brave if you’d ever smelled the Bog of Eternal Stench. It’s, it’s…

Chris: Must be the dog.
Dr. Hathaway: That’s popcorn.
Chris: Yes sir, I know.
Dr. Hathaway: Get it away from me, I can’t stand popcorn, I hate popcorn.
Chris: Good, now I know what to get you for your birthday.
