"A Korean man walked into the currency exchange in New York City with 200,000 Korean won and walked out with $200.
The following week, he walked in with another 200,000 Korean won, and was handed $185.
He asked the teller why he got less money that week than the previous week.
The teller said, "Fluctuations."
The Korean man stormed out, and just before slamming the door, turned around and shouted, "Fluc you Amelicans, too!""
