How many McDonald's hamburgers have been served?

Answer:
There is no way to know for sure. Roughly 245 Billion hamburgers served as of March 31st 2010. I use the history of the number McDonald's used to put on their sign and a complex calculation involving monthly and yearly sales data put out by McDonald's.
