I had a bunch of Canadian dollars I needed to exchange, so I went to the currency exchange window at the local bank. Short line. Just one lady in front of me; an Asian lady who was trying to exchange yen for dollars and she was a little irritated . . . She asked the teller, "Why it change?? Yesterday, I get two hunat dolla fo yen. Today I get hunat eighty?? Why it change?" The teller shrugged his shoulders and said, "Fluctuations". The Asian lady says, "Fluc you white people, too!" ...gonna get heat over this one but it was just too funny to pass up!
