Old-fashioned Anesthesia

A man who had just undergone a very complicated operation kept complaining about a bump on his head and a terrible headache. Since his operation had been intestinal, there was no earthly reason why he should be complaining of a headache.

His nurse feared that the man might be suffering from some post-operative shock, so she spoke to the doctor.

The doctor assured the nurse, "Don't worry about a thing. He has a bump on his head because we ran out of anesthetic halfway through the operation."
