> -There was once a contest of a group of students back in the early days of Monopoly, i think, and their object was to play as long as possible (get an entry in the Guinness Book of Records). After a couple of days of gameplay, they calculated that there was not enough money included in the box to finish their game, so they contacted the founders of Monopoly, and they sent the players immediatly -with a secured transport- more money, so that the game could be finished.

Actually, according to the rules, the bank never runs out of money. If more money is needed than is present, the banker is supposed to use little scraps of paper (I like post-it notes) and write the amounts on them.
