Penises Grown On Rabbits

I've been saving this one for a while. Back in late 2009, about November I believe, Dr. Anthony Atala of Wake Forest University Baptist Medical Center's Institute for Regenerative Medicine announced that his team have successfully grown penises on the backs of rabbits that had their peni previously removed.

This story provides many easy penis joke starters, but the gravity of this work is truly important. They grew these penises on these poor friggin eunice bunnies, I believe on their backs, and then grafted them back in place, with no rejection since the new penises were grown with cells from the little bunny patients themselves.

And apparently what they say about rabbits is true, because all 18 of the new rabbit penises were put to use within 1 minute of being caged with female bunnies.

Out of those 18 horny couples, 4 became pregnant.
