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? Yestoday 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 white guys too!"
No good deed goes unpunished...
