An infinite number of mathematicians walk into a bar...

...The first goes up to the bartender and says, "I'll have a pint of lager, please." The next one says, "and I'll have half of what he's having." The bartender says, "You're all idiots," and pulls two pints.


Also, a round pizza with radius 'z' and thickness 'a' has the volume pi*z*z*a.
