Trivia: In the song "This is Halloween," the two children sing "Tender Lumplings everywhere..." This is a reference to a poem from the film's songwriter/composer/Jack's singing voice, Danny Elfman's, former musical theatrical street troupe, The Mystic Knights of the Oingo Boingo (later to evolve as Oingo Boingo.) The original poem, Tender Lumplings, was "And so my tender lumplings, let my welcome hear you now/Into our flesh-pink home of hearts we greet you with a bow/So entertain we must we may, our pleasure from within/The Oingo Boingo treasure chest of lust and mortal sin."
The Mayor: Jack, I'm only an elected official here, I can't make decisions by myself!
Dr. Finkelstein: That's twice this month you've slipped deadly nightshade into my tea and run off.
Sally: Three times.
