Our happy hour fact to amaze your drinking buddies with.

After a conversation with an attractive woman, men become less able to perform mental tasks.

Dutch psychologists had males and females talk to strangers of both sexes and tested them on word games before and after the interaction. When men spoke to men, or women conversed with either sex, their mental abilities remained unchanged. However, a man gets considerably dumber after he talks to a woman -- and the better-looking the woman, the stupider he becomes.

The researchers posit men can't help but mentally exhaust themselves trying to pick up an attractive woman.

Had we known this earlier, we would have skipped the breakfast buffet at the Hustler Club before taking the SATs.
