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 very 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, "Fluctuate you white people too"
