This can only work in a situation where there is significant excess capacity.
Fisher tells a joke that illustrates the concept in an interesting fashion:
A travelling salesman stopped at a hotel and handed the clerk a hundred dollar bill to be put in the safe, saying he would call for it in twenty-four hours. The clerk, whose name was A, owed $100 to B and clandestinely he used this bill for the liquidation of his debt, thinking that before the expiration of 24 hours he could collect $100 from his own debtor, whose name was Z. So this 100 dollar bill went to B, who, greatly surprised, used it to pay his own 100 dollar debt to one C, who (equally surprised) . . . and so on, and so on, all the way down to Z, who, with much pleasure, returned the bill to A, the clerk, who, in the morning, restored it to the salesman. And then did A, the clerk, stand petrified with horror to see the salesman light a cigar with it.
"Counterfeit," said the salesman, "a fake gift from a crazy friend, Abner; but he didn't put it over, did he?"
