As Lurch's mom is leaving, Thing waves goodbye to her from a hole in a tree. You can see the arm inside the tree.
Morticia: Now isn't this better than shooting apples off of Lurch's head?
Gomez: Oh, much safer, and less expensive. These poor steel-tipped arrows haven't a chance against his head.
Morticia: (about Lurch) He's been terribly depressed ever since he got got that letter from his mother this morning. Not himself at all.
Gomez: How can you tell?
Morticia: He smiled.
Morticia: Well, we always think of you as one of the family, Lurch.
Lurch: A servant.
Morticia: A very good servant.
Lurch: And a liar.
Gomez: And a very good liar! Oh, sorry, I got carried away.
Gomez: Why not have Lurch play dead?
Grandmama: Good thinking!
Fester: You think Lurch could be convincing? He looks so... alive.
Morticia: It was a very sweet thought, darling, but that's true. Lurch is so vivacious.
Gomez: His most outstanding characteristic.
Morticia: Castillians are so fiery.
Gomez: Yes. Cousin Manuelo was a pyromaniac!
Morticia: Do you know she hates Pugsley's octopus?
Gomez: Anyone who'd hate an octopus is warped.
Morticia: She even tries to feed it to Cleopatra.
Gomez: That's inhuman.
Gomez: Tish, when you help me with my coat, it goes right through me!
Morticia: It's impossible.
Gomez: What's impossible?
Morticia: That blondes have more fun.
Grandmama: I won't give up my bed. I just got the nails nicely broken in.
