I'm sorry, people, I just had to share this story. I was having lunch with our Dean today. Before going into administration, he used to be a marine biologist. One of the things he used to show to his students (to an understandably great acclaim) was a penis bone of a walrus. I don't know about you, but I had no idea that penis bones actually existed in nature. I always thought there were part of folklore. The bone the Dean showed me was smaller than the one in the picture but it's still one of the most fascinating things I have ever seen. Just imagine how many things about our human culture would be completely different, if human males had something like this.
