To the right is a duck penis. Apparently it evolved that way to get the girl. What's even stranger, the girl wasn't to be outdone. Her vagina evolved also--to spiral in the opposite direction... Some hypothesize this uncooperative genital response, which occurs only in certain species, is a way to keep guys out--quite literally.
Because really, would you want that stanky hang-down all up inside you?
I didn't write this one for the magazine... but it does make me appreciate how twisted, no pun intended, life can be.
