Mojang mastermind Notch has tweeted that Minecraft has reached the 20 million user milestone, and that if each user weighed 154 pounds, that Minecraft's total player base would equal 25 percent of the weight of the Great Pyramid of Giza. It's an interesting statistic, if somewhat of a stretch, only because it got us thinking about other ways to arbitrarily compartmentalize that sort of information.

For example: Assuming that every Minecraft player contains the human average of 1.3 gallons of blood, Minecraft's player base equates to 39.9 regulation olympic-sized swimming pools full of vital fluids. Math is neat, isn't it?
