Currency Exchange

I had a bunch of US dollars I needed to exchange so I went to the Currency Exchange window at the local bank. Short line -- just one guy in front of me.

The guy in front of me was an Asian guy who was trying to exchange yen for dollars and he was a little agitated.

He asked the teller, "Why it change? Yesterday I get two hunat dolla of Yen - today I get hunat eighty? Why it change?"

The teller replies, "Fluctuations."

The Asian guy says, "Fluc you white guys too!"
