The ground rules are to give a famous (or at least somewhat known) quote that really wasn't uttered, and definitely not uttered by the person it's attributed to. That's important - that the quote wasn't really uttered by the person it's usually attributed to. The object is to guess who the quote is usually attributed to. Bonus points for knowing the true story behind the quote. Just to make the idea clear, I'll give the first quote (an incredibly easy one).
