An Asian lady (think "Sue" from Ass Monkey garage)was trying to exchange yen for dollars at her bank and was getting irritated
She asked the teller, "Why it change? Yesterday, I get two hunat dolla for 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 boy"
