So let me thrown down the gauntlet and challenge you... the game below, "The Impossible Quiz" will take a short while to load - but it's definitely worth the wait!
I warn you now - do not attempt the following if you've got no time to waste... because once you start, you will not be able to stop. I chanced upon it, and decided to give it a try - hours later, I'm embedding it on my blog!
So - do please let me know how you go... and how long it took for you to get through it - if ever you do. :)
