I need to learn the language of the dentists

Seriously, I was at my appointment today and while my dentist was poking around in my mouth he was telling things to his little assistant. Like random numbers and words, I was so confused, they were speaking in freaking code or something! I need a piece of this, so when I go to the dentists again I'll be able to talk back to them in code. Sure, it'll be hard to speak around fingers and people might get hurt, but I'll be part of the fun! I don't really know how I'm going to learn this code, but I am committed. For now. I'll probably find something more interesting/fun to do tomorrow.
