A clinical class had just arrived at our nursing home and some of the nursing students noticed that the nurses were all wearing pins on their uniforms. They had noticed that the pins were shaped like apples.
"Excuse me, " a student said to a RN. "Every nurse has a pin on that looks like an apple. Did you all graduate from the same nursing school
"Oh, no," answered the RN. "We wear them to keep the doctors away!"
