Why is the penis shaped like that? [T]he human penis is actually an impressive “tool” in the truest sense of the word, one manufactured by nature over hundreds of thousands of years of human evolution. You may be surprised to discover just how highly specialized a tool it is. Furthermore, you’d be amazed at what its appearance can tell us about the nature of our sexuality.

This news item turned out to be a hoax. Has Reuters been fooled again? I certainly smell a rat... (I know the original mefi link pointed to the BBC, but the BBC picked it up from Reuters)
