The law of unintended consequences, yet again.

Jackie links to Amy's transcript of Bill Maher:

A new eight-year study just released reveals that American teenagers who take "virginity" pledges of the sort so favored by the Bush administration wind up with just as many STDs as the other kids.

But that's not all -- taking the pledges also makes a teenage girl six times more likely to perform oral sex, and a boy four times more likely to get anal. Which leads me to an important question: where were these pledges when I was in high school?
