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 $250,000.00, and three years of research, they concluded that the reason was to give the woman more pleasure during sex.
Russians, unsatisfied with these findings, conducted their own study.
After two weeks, several bottles of Vodka and a cost of around 59 Rubles, they concluded that it was to keep a man's hand from flying off and hitting him in the forehead.
