Btw, before anyone gets self-rigtheous on me, my Asian gf and her teenage sons thought this was hilarious...

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 looks shocked, then says, "Well fluc you white people too"
