A Chinese man walks into an American bank and sees the man in front of him exchanging some swiss francs into a good chunk of change. Remembering the leftover walk-around money from his vacation, he returns with roughly the same amount of francs the next week and asks the teller to exchange them. Upon receiving a sum much smaller than anticipated, he demands to know why. ""Fluctuations."" The teller says. At this, the Chinese man turns red in the face and yells, ""Oh yeah? Well fruck you yankees too!""
