Say, What?

Last night, while Scott played Halo with a bunch of guys from work, I was watching the Colbert Report, I think. Anyway, he brought up this study that was done that found women's voices get sexier when they are ovulating. They recorded women counting to ten during different times in their cycle and found that their voices became sexier while they were ovulating. Huh? What I would really like to know is, whose bright idea was this? Who had the dumb thought, "Hey I wonder if that woman is ovulating, because her voice is sooo sexy!" And who put up the money to test something like this? Seriously, WHY? What's the point? Can someone explain this to me, because, frankly, I don't get it.
