Having a baby isn't so bad. If you're a female Emperor penguin in the
Antarctic. She lays the egg, rolls it over to the father, then takes off
for warmer weather where she eats and eats and eats. For two months, the
father stands stiff, without food, blind in the 24-hour dark, balancing
the egg on his feet. After the little penguin is hatched, the mother
sees fit to come home.
