I was in the bank the other day and this asian lady was wanting to change her yen to dollars and she was a little irate.
  She asked the teller "why it chane yedaday i get two hunat dolla for my yen toyay i get one an eighty dolla for my yen'
   The teller says its "fluctuation"
 The asian lady says " fluc u assralians to"

Good one. 

worth a large smile
