Today's word is................. Fluctuations!

I will never hear or see this word again without thinking of this joke.  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 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, "Fluc you white people too"
 
(You know you're laughing...)
