An Asian man walked into the currency exchange in New York with 2000 Japanese yen and walked out with $72.
The following week, he walked in with 2000 yen, and was handed $66. He asked the teller why he got less money than the previous week.
The teller said, "Fluctuations."
The Asian man stormed out, and just before slamming the door, turned around and shouted, "Fluc you Amelicans, too!"
