The dentist said to me as she started drilling into my front tooth - without first using Novocain.
Just as I started to believe she wasn't going to hurt me, she got close to the nerve and I could feel the pain. "Oh, I know, I know," she said to me. "Don't worry, it's okay."
Seriously? Sure, it's okay because she's the one with the drill and I'm the one in the chair with white knuckles.
