An Asian lady was trying to exchange yen for dollars in a bank. 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!"
