The socks

A merchant went to a farmer to get a pound of butter. The farmer insisted on swapping the butter for a pair of wollen socks. When the merchant reported this to his wife, she said - i'll unravel some wool from our bedspread and knit him pair of socks. When it was finished a pair socks was exchanged for a pound of butter.
When the merchant needed more butter, his wife again unravelled more of the bedspread and knit more socks, which were exchanged for butter. Finally she had enough wool for one sock. The merchant took the sock to farmer and asked for half pound of butter for it.
"Nothing doing", replied the farmer. "I'll give you a full pound of butter. You see, I really dont wear socks. My wife unravels the wool and uses it for knitting a bedspread, and there's just enough in this one sock to finish it. "
