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 fo 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!"
