"Male Muscovy ducks have ballistic corkscrew penises. Yes, ballistic. It's about a quarter of the duck's length and
it shoots out in a third of a second. And of course there're spines and such things added for good measure. Females? Well
their vaginas have dead ends and spirals in the opposite direction to the male's corkscrew.
Then there's the honeybee penis that sort of explodes (or rather, is ripped away. Yeah, he dies). And the bed bug that
doesn't use a nice lady-receptor but just stabs the female and leaves his sperm in her abdomen. And of course if we're
talking about giant penises... don't forget the elephant who has an enormous one that can be used for support. Yup, fifth leg
right there. And it can even grab things."
