Today's word is "fluctuations."
I was at my bank today. There was a short line, just one Asian lady in front of me trying to exchange yen for dollars. 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 angrily, "Fluc you white people, too."
