In 1993, the American Government funded a study to see why the
head of a man's penis was larger than the shaft. After one year
and $180,000, they concluded that the reason the head was larger
than the shaft was to give the man more pleasure during sex.

After the US published the study, France decided to do their own
study. After $250,000, and 3 years of research, they concluded
that the reason was to give the woman more pleasure during sex.

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