The Pandaren Monk started as an April Fool's joke for "WarCraft 3" and has since grown to become apart of the "WarCraft" canon. The latest appearance of the martial arts-saavy, panda-esque race was as an in-game pet in "World of WarCraft" (pictured on the right). The Pandaren Monk was sold for $10 in Blizzard's online store, with half of the proceeds going directly to the Make-A-Wish charity. The end result? 1.1 million bucks were donated to the charity. That's a lot.
Actually, that's astronomical when you consider that $5 per in-game panda would require 220,000 separate purchases. Figuring an annual subscriber base of around 12,000,000 users, that works out to about 2% of the "World of WarCraft" population walking around with a Pandaren in tow. See, everybody wins!
