Today's word is.................. Fluctuations

I was at my bank today; there was 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"

(You know you're laughing...)
