infinite mathematicians enter a bar. the first orders a pint of beer, the second orders half a pint. the third orders a quarter pint, and the bartender cuts them off there and just pours them two pints
after a time the mathematicians indicate they're ready for another round. as before, the first one orders a pint and the second orders a half. when the third orders a third of a pint the bartender says "actually i think you've all had enough for tonight"
infinite mathematicians are in a bar, nursing epsilons of beer from a previous order and getting a bit mischievous. catching the bartender's attention, the first orders a pint. the second orders two pints, the third three pints and so on. after a while the exasperated bartender pours a twelfth of a pint out of the mathematicians' glasses, at which point a brawl breaks out
joke defense
@orrery why? the first joke uses 1+1/2+1/4...=2 to establish that the lot of them asking in a convergent series means the lot of them get two pints altogether, to split as they first wanted. then the third joke, using 1+2+3...=-1/12 (controversially, hence the brawl), would imply that the lot of them would lose a total of a twelfth of a pint

@typhlosion Somehow I came away with the reading of the third joke that you were implying that each mathematician needed to lose a twelfth of a pint, which is why I spoke up. I got the humor; I just misread what you typed.

@orrery further, since it's stated in the setup that there are *epsilons* of beer left in the glasses, it would probably take more than one glass worth of dregs to equal a twelfth of a pint
