I saw the above as a search term that someone had used to get to my blog and it made me chuckle in a hearty fashion.
Me thinks someone is getting nature mixed up with algebra, or mathematics. I remember from my school days that two minuses most definitely make a plus. -x multiplied by -x makes x squared. (does anyone know how to do a squared sign on a normal keyboard, you know the little number 2 in the corner)
But I'm damn sure the same principle doesn't apply to the birds and the bees. Or to Humans. Life just doesn't work like that.
It would be too easy.
