The penis study:

The American 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 US published the study, the French decided to do they're 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.

Newfoundlanders, unsatisfied with these findings, conducted their own 
study. After 2 weeks, 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!
