“Be your own dentist!”
“Waiting for your buddies to get laid is right up there with hanging out in a dentist's office.”
“My dear Algy, you talk exactly as if you were a dentist. It is very vulgar to talk like a dentist when one isn't a dentist. It produces false impression”
“It doesn't really matter whether you grip the arms of the dentist's chair or let your hands lie in your lap. The drill drills on.”
“If you don’t care about something, one way to demonstrate your feelings is to say the word and then repeat the word with the letters S-C-H-M replacing the first letters. Somebody who didn’t care about dentists, for instance could say ‘Dentist, schmentists.”
“I’ll wait until your mouth is full of food before I ask you a question. I’m like a dentist.”
