A veterinarian was feeling ill and went to see her doctor.

The doctor took an extensive medical history and then inquired about
her symptoms and complaints.

She interrupted him, "Hey look, I'm a vet. I don't need to ask my
patients all these questions. I can tell what's wrong just by looking."

She smugly added, "Why can't you?"

The doctor nodded and said, "Okay, I'll take your challenge."

The doctor quickly performed a physical exam, being careful not to
ask any questions. He then picked up a pad, wrote a prescription and handed it to her.

"There you are. Take these pills four times a day for ten days.
If this doesn't work, come back, and we'll put to sleep."
