When we take tour of a new beta site, we are shown a question "How to prevent unicorns from eating daisies?". For example try Interpersonal Skills Stack Exchange. Is this a real question asked by users or a question created by the developers to show as an example? If this is a real question, on which site did Unicorns eat daisies?
On a side note, it is a big coincidence that the user posted the question and users posted answers have exactly the same gravatar.
