the agenda of homosexual flightless waterfowl - Colbert threatdown re book Tango Makes Three. Yay Roy and Silo! I remember reading about them.
booklist: Roy and Silo were "a little bit different" from the other male penguins: instead of noticing females, they noticed each other. Thus penguin chick Tango, hatched from a fertilized egg given to the pining, bewildered pair, came to be "the only penguin in the Central Park Zoo with two daddies."
and March of the Penguins - "I haven't seen it, but we all know who marches."
