Patient allergies joke

An element of the admission procedure in the hospital where consultant Tim Westwood worked, was to ask the new patients if they suffered from any allergies.

On one particular occasion Tim asked an elderly woman if she had any allergies. The old dear responded by saying that she was unable to eat bananas.

Tim received a considerable surprise later in the day when a very irate son came out of the ward demanding, 'Who's responsible for labelling my mother 'bananas'?
