If you're a card-carrying Minecraft player, consider yourself in good company. Markus Persson, the game's mastermind (better known by his online handle, Notch), tweeted that the blocky sandbox game has hit a significant milestone: 20 million registered users.

His first tweet was relatively mild, saying "Minecraft now has 20 million registered users. At 70 kg each, that's 25% of the weight of the Great Pyramid of Giza." He followed it up with a slightly disturbing conversion. "At 4 liters per day, it would take a million years to drink 20 million liquidized humans. Just saying. I'll stop now."

Those registrations didn't all translate to paid users, which Notch noted in a similarly tongue-in-cheek stat. "23.23% also bought the game. Extrapolating, we find that 76.77% of the internet will register for things they don't want."

That's more than 4.6 million paid copies, if you don't feel like crunching the numbers yourself.
