Research data required

A Psychiatric Professor has found that there are two sizes of penis
amongst UK men.

There are those which fall within the normal size range and those which
are less than two inches when erect.

The professor has appealed for help to continue his research.
Could all men in the UK with extremely small penises make themselves
known over the next six weeks by flying a white flag with a red cross
from their cars ?
