"The Science Of Beer, scientists at the USDA suggested that men should take a look at their beer consumption, considering the results of a recent analysis that revealed the presence of female hormones in beer.
The theory is that drinking beer is turning men into women.
To test the theory, 100 men were each fed six pints of beer. It was then observed that 100% of the men gained weight, talked excessively without making sense, became overly emotional, couldn't drive, failed to think rationally, argued over nothing, and refused to apologize when wrong.
No further testing is planned." --contributed by Bugman1109
