Very funny joke? Urgent!

A patient went to see a doctor for the first time.

"Did you consult anyone about your illness before you came here?" The doctor asked.

"Just ask the owner of the drugstore around the corner," the patient replied.

Doctors hate that people who are not doctors often give medical advice. He made no secret of this: "What bad idea did that fool give you?"

"He asked me to come to you."
