The whole article is kind of salacious, but check this part -
"In 1998 more penguin depravity came to light, when people observed adélie penguins using stones to pimp out females for prostitution. They also reported that some of the prostitute penguins tricked the males into thinking they would have sex by performing an elaborate courtship ritual, then run away with their stones."
Yeah, it's a good things that sort of thing wouldn't happen with humans... lol.
