The Vet Sees the Doctor

A Veterinarian was feeling ill and went to see her doctor. The
doctor asked her all the usual questions, about symptoms, how long
had they been occurring, etc., when she interrupted him: "As a vet - I
don't need to ask my patients all kinds of annoying questions: I can
tell what's wrong just by looking. Why can't you?"

The doctor nodded, stood back, looked her up and down, quickly wrote
out a prescription, handed it to her and said, "There you are. Of
course, if that doesn't work, we'll have to have you put to sleep."
