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
@typhlosion ... not to nitpick the joke, but he should only pour the twelfth of the pint out of the first mathematician's glass.
This won't stop the brawl, mind you, but it will be more accurate. ^v^
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
joke defense
@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.
