Can we allow questions (with a disclaimer) that are not-serious, as in based on a fictional claim? To give concrete examples,
J.K.Rowling claims in Harry Potter that if you jump into a fireplace, you can move to a different one if you say the new place before you go in. Does anyone have anecdotal evidence for this?
Or one from Lewis Carroll:
Lewis Carroll claims in Through the Looking-Glass that if you go through a mirror, you will enter a world where animals speak. Is this true?
You would have to have a disclaimer that says something like, "Don't take this claim or answers seriously." We'd also have a separate tag (like "fun") so people could block such questions.
I don't know if this has been tried before, but I know something similar has been done on some other SE sites. I couldn't find anything related on meta, except perhaps Should we allow the Santa question?
