We wanted to lay out a strange puzzle for you on today's podcast, then answer it tomorrow. But we forgot to mention it. So here it is:

Where is all the U.S. currency?

According to the Federal Reserve the total amount of U.S. currency out there is about $900 billion. We're talking real currency, dollar bills, $100's, $20's etc.

That works out to about $3,000 per person. Ok now open your wallet, how much do you have? Not a lot, right? So where is all the cash?

Don't look it up on the internet, that's no fun. Just think about it. We'll have the answer on Morning Edition and a longer extended-dance-remix on the podcast for Friday.
