一只张牙舞爪的虫子

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 dollah fo yen. Today I get hunat eighty?? Why it change?"
The teller shrugged his shoulders and said, "fluctuations".
The Asian lady then said, "Fluc you white people, too!"
And then she stormed out.
