Several years ago the United States funded a study to determine why the head on a mans penis is larger than the shaft.

The study took two years and cost over $180,000. The results of the study concluded that the reason the head of a mans penis is larger than the shaft was to provide the man with more pleasure during sex.

After the results were published, Germany decided to conduct their own study on the same subject. They were convinced that the results of the US study were incorrect. After three years of research and costs in excess of $250,000, they concluded that the head of a mans penis is larger than the shaft to provide the women with more pleasure during sex.

When the results of the German study were released, Australia decided to conduct their own study. The Aussies didnt trust the US or German studies. So after nearly three weeks of intensive research at a cost of around $75, the Aussie study reached a conclusion.

They came to the final conclusion that the reason the head on a mans penis is larger than the shaft is to prevent his hand from flying off and hitting him in the forehead.
