The theory is that beer contains female hormones (hormones contain phytoestrogens) and that by drinking enough beer, men turn into women.

To test the theory, 100 men drank 8 pints of beer each within a 1-hour period. It was then observed that 100% of the test subjects:

Argued over nothing.

Refused to apologize when obviously wrong.

Gained weight.

Talked excessively.

Became overly emotional.

Couldn’t drive.

Failed to think rationally.

Had to sit down while urinating.

No further testing was considered necessary
