I was at my bank today waiting in a short line. There was just one lady in front of me, an Asian lady, who was trying to exchange yen for dollars. It was obvious she was a little irritated. She asked the teller, "Why it change? Yesterday, I get two hunat dolla of yen. Today I only get hunat eighty? Why it change?" The teller shrugged his shoulders and said, "Fluctuations." The Asian lady says, "Fluc you white people too!"
