This one's making the rounds, so for those of you who haven't seen it... an actual whale penis.
What isn't making the rounds is the rest of the story. Turns out this specimen -- or whatever you want to call it -- was "harvested" by a gent from Iceland who studies animal penii. And he's founded (the caption said "erected"; someone at Reuters had some fun) the Icelandic Phallological Museum. He has units from dozens of various animals from Iceland.
Well, everyone needs a hobby of some sort.
