The BBC mentioned a pre-historic penguin found in Peru last night. It lived over 30 million years ago and stood over 1.5 meters tall (almost five feet)! This is definitely a setback to penguins’ ongoing PR campaign to present themselves as comical, peaceful, flightless birds who like to tap dance, surf and listen to the soothing narration of Morgan Freeman. This could explain where their vindictive streak against Batman may have originated.
Palentologists' best rendering of at what the pre-historic penguin may have looked like. They weren't available for comment on the rare South Pole walrus found at the dig.
