Why it's important to understand English:

When I got back from Montana last week I had a bunch
of Canadian dollars I needed to exchange, so I went to
the currency exchange window at the local bank. It was
a short line with just one guy in front of me...an
Asian guy who was trying to exchange yen for dollars
and he was a little irritated! He asked the teller,
"Why it change?? Yestoday, I get two huna dolla of
yen. Today I get huna eighty?? Why it change?" The
teller shrugged her shoulders and said,
"Fluctuations". The Asian guy says, "Fluc you white
people too!"
