man of what?

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, what if a patient said, "How's my back tooth?" I'd just look at it with my X-ray vision and say, "Oh it's okay," then the patient would probably say, "Aren't you going to take an X-ray, stupid?" And I'd say, "Aw fuck you, get outta here," and then he probably wouldn't even pay his bill.
