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 an intestinal one, there was no
earthly reason why he should be complaining of a headache.

Finally his nurse, fearing that the man might be suffering from
some post-operative shock, spoke to the doctor about it.

The doctor assured the nurse, "Don't worry about a thing. He
really does have a bump on his head. About halfway through the
operation we ran out of anaesthetic."
