Via Andrew Sullivan, this story on gay Penguins:
A good friend of mine worked on “Rock Island” at the Baltimore Zoo for several years after college. Rock Island is the home of the zoo’s colony of African (Black-footed) penguins. If memory serves, African penguins mate for life rather than seasonally — which included the for-life pair of Bob and Dave. Apparently some of the (heterosexual) mating pairs weren’t terribly adept at caring for their eggs or young, so when these particular pairs would produce an egg the zoo staff would snatch if from their nest, replace it with a fake, and put the real egg in Bob and Dave’s nest because they were very good at caring for an egg. My friend used to say that when Bob and Dave would come back to their nest and find an egg there they’d look at each other in a puzzled way as if to say, “Hmmm… one of us must’ve had an egg.” Then they’d go about the normal business of caring for it as though it were theirs.
Definitely “Heh” worthy.
