Gas or Novocaine?
When you go to the dentist to get your cavities drilled, the doctor will ask you, "Novocaine or gas?" meaning, "Would you prefer to have your gums numbed or your brain temporarily disabled to the point that the discomfort in your teeth will only confuse instead of hurt you?" The only correct answer to this question is, "Both." The dentist and his assistant will at first laugh at your answer, but if you lie on your back with a straight face there will be an uncomfortable silence for a moment, and then they'll give you both. After a few times, they might try to tell you that your insurance will only cover one or the other. Just tell them you'll pay the $20 for gas out of pocket. They rarely send the bill.
