One Halloween during my internship year I got home late on Halloween. I had my lab coat and stethoscope on me and trick-or-treaters came to the door, so I decided to greet them. I gave out candy to the first couple of kids and then the next one says "hey mister, are you a real doctor?" all excited. I said "yes I am" to which he replied "oh" and then hung his head and walked away.
