The Rules: One player thinks of something, anything at all. The other players ask twenty questions about that thing, after which time they must make a guess as to what that thing is.

The answer is almost always an attractive pop star or an actor, so, if any of today's youth are reading this, we suggest that you think outside the box. Pick something like "Shrödinger's Cat" or "bellybutton lint." Another pro tip: don't just use your questions on guesses, unless you're totally sure. If you start using your questions on guesses too soon, you'll be out of questions before you know it.
