Financial Cryptography

an infinite number of maths students...

Chris told me this one last night: an infinite number of maths students go into a bar, and decide to have some fun with the bartender. The first says "I'll have a pint." The second says "I'll have half a pint." The third: "I'll have a quarter of a pint," and the fourth "and an eighth..."

To which the bartender says, "you guys are pathetic, I'll just give you two pints."

(No, I've no idea what the TV show is about...)
