Audio problem: With Morticia in his arms, he says "And I dropped you...only once." If you watch his profile, you can see that his face never moves. Hard to believe especially when you know he had an animated face.

Continuity mistake: After Mr. Hilliard goes through gate and nears the house, it's really at the real house. A second later, he's approaching the now-familiar front porch on the studio set. This is easy to tell because the layout of the two porches are radically different.
Morticia: Think of Romeo and Juliet.
Gomez: They died.
Morticia: Oh, but what fun they had those last three days.
Trivia: John Astin (Gomez), Carolyn Jones (Morticia) and Ted Cassidy (Lurch) are the only actors to appear in all 64 episodes of the show.
Question: How was effect of the light bulb that lit up whenever Fester put it in his mouth achieved?
Answer: Basically from what I understand, they stuck the innards of a small flashlight into the base of the bulb and put a little switch on it. When he put it in his mouth and bit down, his teeth would hit the switch, which would turn on the flashlight and made the bulb light up.
