8. Firefox Kitchen Sink

What you get: A single pixel on the upper-left hand corner of your monitor will turn black when you mouse over a block that contains a mine. Get the high score on the family computer!

What you get: Launched into a nifty flight simulator that glides you over the surface of a planet (the moon?) and shows you Excel developer credits. (I don't have a copy of Excel 97 any more, but definitely got this puppy to work back in the day.) Thanks to EggHeaven for reminding us of the steps to get there.
