Dr. Finkelstein
- Jack Skellington: [singing] All these people that you're hurting, oh, good doctor, it's disconcerting/ Doc-tor please! You're thinking is all wrong!
- Dr. Finkelstein: [singing] In a moment, finally, you'll be gone!
- Jack Skellington: [singing] You're thinking is evil, your thoughts are all bad/ The thing that you work for is no more than a cad!
- Jack Skellington: [singing] When finally I get that foul brain out of you/ You'll see no more foe, but a friend that is true
