There is a man who visits Great Britain on a vacation from his home country:
China. The first day he exchanges some Chinese money for twenty British pounds.
That day he paints the town red and needs to go to get more money.
The next day he goes back to the same currency exchange office and gives the
same amount of Chinese currency, but only gets 19 pounds in return. In broken
English, he says to the clerk, "Yestaday, I give you Chinese money and you give
me 20 pound. Today, I give you same money, you give 19."
The clerk replies, "Sir, it's the market. Fluctuations."
The Chinese man gets an enraged look on his face and yells back, "Fluck you
Asians!!? Well Fluck You British!!"
