Jekyll Hyde, DDS

Most dentists are jovial and compassionate. But if jolly/benign is not your bag, here are three surefire tactics to turn your dentist into a raving sadist. 

1. Say: “Hey, doc. ‘Is it safe?’ Ha ha ha ha!”
2. Go on and on about Steve Martin’s character in “Little Shop of Horrors.”
3. Ask for nitrous oxide the next time you get your teeth cleaned. Halfway through the procedure, fall out of the chair.
