I LOVE this scene:
"They have to do that to remove the jaw... consider yourself very, very lucky!"
"Does, uh, THAT, have an appointment?"
"I'm sure I need a long, slow root canal"
"She can't really see who you are but she knows, she knows the sound of your voice, and if you tell her where it is the problem, she eventually works her way back and she finds the trouble and she does it"
"CANDY BAR! CANDY BAR!"
