Fluctuations

An Asian man walked into a currency exchange in NYC with 2000 yen and walked out with $72. The following week he again walked in with 2000 yen, but only received $66. He asked the teller why he received less money than the previous week.

The teller said, "Fluctuations."

The Asian man stormed out, and just before slamming the door, turned around and said, "Fluc you Amelicans, too!"
