How many?

Yesterday, I was wondering with a friend how many mathematicians there are on the globe (where we defined a mathematician as someone who has published a mathematical paper over the las ten years, and curiously enough cut ourselves out). Our first estimation was something like 1000000 but I have not been able to find some reliable figures on the net to confirm it. However, I did stumble upon this during my search which really made me laugh hard, although I've heard quite a few mathematical jokes in the past four years.

This is one of the best pranks I've seen in years. According to www.spiegel.de, roughly 1.2 million copies of this "New York Times Special Edition" have been distributed in the bigger cities of the US. A pdf of the paper is available on their site, the download's really worth it, even if you just read the headlines and look at the ads!
