I think the point here is that he initially did it as a joke to see if people would actually donate him money... he was pi**ing himself that people were so stupid enough to do it, yet kept on asking for more... It was only after many people tweeted him back saying what he was doing wasn't right that he said he was going to donate it to charity...

So it wasn't like he did it to begin with to make money for charity...
