We know who the Teenage Mutant Ninja Turtles are, but this could paint them in a strange light.
In the latest podcast from the QI Elves entitled "There's No Such Thing As A Fish", it's revealed whilst talking about turtle penises (as you do), that a cross-section of a turtle's penis looks very like the head of a ninja turtle.
Well, is that right?
I'm sorry, I've tried. It can't be unseen.
For some context, other turtle penis chat or other amusing and interesting facts on how to flirt, listen to the episode here. (The turtle chat is at 19:25)
