Beryl: Paranormal? Is that what they're calling your kind these days?
Otho: Don't mind her. She's still upset because somebody dropped a house on her sister.
Barbara: We're very unhappy.
Juno: What did you expect? You're dead.
Beetlejuice: I'm the ghost with the most, babe.
[Beetlejuice angrily kicks a model tree and it falls over.]
Beetlejuice: Nice fucking model!
Adam: This book reads like stereo instructions. Listen to this. Geographical and temporal perimeters. Functional perimeters vary from manifestation to manifestation.
Bernard: Delia, you are a flake. You have always been a flake. If you insist on frightening people, do it with your sculpture.
Beetlejuice: It's showtime.
Adam Maitland: What are your qualifications?
Beetlejuice: Ah, well, I attended Juliard, I graduated from Harvard Business School, I travel quite extensively, I lived through the Black Plague and I had a pretty good time during that, I've seen The Exorcist about 167 times and it keeps getting funnier every single time I see it, not to mention the fact that you're talking to a dead guy! NOW WHAT DO YOU THINK?
Beetlejuice: Alright, let's get down to business! I got a card around here somewhere. Here, here, who do I have to kill? Here, hold that for me, would you?
Barbara Maitland: Whoa! Ah!
Beetlejuice: There you go!
Adam Maitland: You don't have to kill anybody!
Beetlejuice: Ah! Possession! Good! [Beetlejuice's voice comes out of Barbra's mouth] Learn to throw your voice. Fool your friends! Fun at parties!
