You know, the sad part is that I bet that if Nintendo were to accept real donations for the stated purpose of 'fulfilling Wario's Dream of being rich', they would actually drum up a serious amount money. People would donate because they're fans of Wario, or fans of Nintendo, or perhaps because they want to make an ironic statement on the concept of crowdsourcing. Whatever the reason, so many people would donate just to be in on the joke that Nintendo would likely make millions.
Perhaps Nintendo should do that and then announce that Wario has decided to donate all his wealth to Child's Play.
