Quote by Jack Handey, Deep Thoughts

At first I thought, if I were Superman, a perfect secret identity would be "Clark Kent, Dentist," because you could save money on tooth X-rays. But then I thought, if a patient said, "How's my back tooth?" and you just looked at it with your X-ray vision and said, "Oh it's okay," then the patient would probably say, "Aren't you going to take an X-ray, stupid?" and you'd say, "I did," and then he probably wouldn't even pay his bill.
