The French Government funded a study to see why the head of a
man's Penis was larger than the shaft. After 1 year and $180,000, they concluded that the reason that the head was larger than the shaft was to give the man more pleasure during sex.

After the French published the study, the Italians decided to do their own study. After $250,000 and 3 years of research, they concluded that the reason the head was larger than the shaft was to give the woman more pleasure during sex.

The Polish, unsatisfied with these findings, conducted their own
study. After 2 weeks and a cost of around $75.46, and 2 cases
of beer, they concluded that it was to keep a man's hand from
flying off and hitting himself in the forehead.
