A Chinese man is in an Australian bank when he sees an Australian cashing in 100
American dollars, getting 143 Australian dollars in return. Remembering that he has
some American money at home (left over from his last holiday), he returns the
next day to the bank to cash his money in.
"Here is 100 American dollars, please exchange it for Australian dollars".
The teller gives him 133 Australian dollars.
"What's this? Yesterday you gave an Australian man 143 dollars for the same
amount, but now you give me only 133. Why?"
Teller: "Fluctuations".
"Yeah? Well, fluck you Aussies too!!"
