The school principal threatens to expel the children after they've been playing with dynamite caps. Morticia hears that Sam Hilliard, former truant officer, is now running a private school, Mockridge Hall. She wants to get the children enrolled. Mockridge Hall is strapped for cash and Mr. Hilliard can't turn down Gomez's offer of $10,000 tuition. When Pugsley and Wednesday bring their pets to school, he expels them. Gomez thinks he's cracked under the pressure of the money problems and he buys the school to run it properly. He renames it Addams Hall and Mr. Hilliard resigns immediately, so Morticia persuades Gomez to take over. The parents of the other pupils insist that Mr. Hilliard return or they'll take their children out. Morticia is touched by their loyalty to Mr. Hilliard (actually, they're terrified of Gomez). Gomez brings him back with a promise not to interfere. Wednesday and Pugsley decide they prefer their old school, and return there.
