Why do we need trivia? It's really just the accumulation of random pieces of knowledge that often have no practical use - they just float around in your head aimlessly, like space junk orbiting the Earth. Yet the world of trivia does have one thing going for it: it's a measure of of how much stuff one knows. If you've been exposed to a variety of different backgrounds, fields and cultures, chances are you'd make a competitive trivia player.

So "Jeopardy!" fans, get ready to test your knowledge. The following questions are related to movies, T.V. shows, outer space, languages, tennis and everything in between. The questions increase in difficulty as the quiz progresses, with the final question bordering on insanity (write a comment below if you get it!). Good luck!
