Good thing Ward Chruchill's out...

My anthropology professor at Berkeley said that nature follows the Bell curve in sexual behavior - and most of us, if given the chance, fall in the middle as to sexual orientation. So Harry the Penguin is acting normally, and it's our culture with it's obsessions on an exclusive behavior which is abnormal. He's an emeritus professor now, very old, but I think he'd find this story amusing and present it to his physical anthropology class just to annoy the ideologues and absolutists.
