I didn't know where to put this factual information. Yesterday I bicycled by a surgeon's office...

Considering the many who have their head in such position, he has found a lucrative profession if, that is, his patients can find their way to his office.

Dr. _______
Oral Surgery
Entrance at Rear

For those of us with our heads and mouth where they should be, an extraction in his office would be more than just a pain in the butt.
