Rules of the office

A new patient was quite upset when the doctor's nurse led him to a small, curtained cubicle and told him to get out of his clothes. "But I only want the doctor to look at my ingrown toe nail!" he protested.
"Our rule is that everyone must undress," replied the nurse as she handed him a very skimpy gown.
"That's a dumb rule," grumbled the patient, "making me undress just to look at my toe."
"That's nothing," growled a voice from the next cubicle. "I just came to fix the phone lines!"
