Economics Joke

Here’s a tip. It won’t make you a fortune, but it’ll be well worth your while.
Take a look at the dollar bills in your wallet. To the right of George Washington (the first President of the United Sates), and downward and leftward of the round green seal, you will see a date. Most of your bills will say “SERIES 2003 A.” But you’ll still find a few that date back to “SERIES 1999.”
Hang on to them! Any sophisticated economist will tell you that, because of inflation, 1999 dollars are worth considerably more than 2003 dollars. Do this consistently. Over time, you’ll find that little extra effort adds up to a tidy sum.
I figure as long as I have my expertise in economics, I might as well share it with my friends.
