I had a bunch of Canadian dollars I needed to exchange for some real money (USD), so I went to the money exchange window at the local bank. It was a short line, with just one guy in front of me. He was an Asian guy who was trying to exchange yen for dollars and he was a little agitated.

In a thick accent, he asked the teller, Why it change? Yesterday I get two hunat dolla fo yen – today I get hunat eighty? Why it change?

The teller says, Fluctuations.

The Asian guy says, Fluc you Americans too!
