Banking humour

I had a bunch of American dollars I needed to exchange so I went to the currency exchange window at the local bank . I chose the shortest line...just one guy in front of me. He was an Asian guy who was trying to exchange Yen for dollars and he was a little agitated. He asked the teller, "Why IT change? Yestoday I get two hunat dolla fo yen. Today I get hunat eighty?" The teller says, "Fluctuations." The Asian guy says, "Fluc you white guys too!"
