How tall is a penguin? A man rushes into a bar and screams at the bartender, "How tall is a penguin?" The bartender looks at him weirdly and says, "Excuse me?" The man repeats, "How tall is a penguin?" The bartender motions with his hands. "Uh, about this high." The color drains from the man's face as he says, "Oh shit I just ran over a nun."
