Slutty Chicks = Bigger Balls

Who says science is boring?

It turns out that if the women are loose, the men grow huge nads and their brains shrink. Sounds 'bout right, don't it?

For some male bats, sexual prowess comes with a price - smaller brains. A research team led by Syracuse University biologist Scott Pitnick found that in bat species where the females are promiscuous, the males boasting the largest testicles also had the smallest brains. Conversely, where the females were faithful, the males had smaller testes and larger brains.

"If female bats mate with more than one male, a sperm competition begins," Pitnick said. "The male who ejaculates the greatest number of sperm wins the game, and hence many bats have evolved outrageously big testes."

What kind of job is that? You've seen those freaks judging the dog shows, yeah, but these are bats. Anyway – "outrageously big"? Jealous much?

Promiscuity is known to make a difference in testicle size in some other mammals. For example, chimpanzees are promiscuous and have testicles that are many times larger than those of gorillas, in which a single dominant male has exclusive access to a harem of females.

Interesting... I wonder where that puts Shaquille O'Neal? Osama bin Laden?

But then consider the case of President Bush – he's got one faithful, schoolmarm of a wife and gigantic fucking balls.
