Doctor of Patientology

I had a patient who is kind of confused and I was hoping that he was getting better. I told him I one day that I was the doctor and I wanted him to remember who I was. The next day I asked him about it.

Me: "Do you know who I am?"

Patient: "Yes. You're the physician, and you specialize in.... caring for patients."

Actually, I did my fellowship in caring for patients.
