There is a guy in a van down by the river.  Bring a plain brown paper bag with you down to the van.  Knock 5 times on the van's sliding door.  When he asks for the code tell him "drink more ovaltine".  The van door will open and a hand will come out.  Hand your bag to the hand.  He will fill up the bag with crisp 20 dollar bills and hand your bag back to you.  Whatever you do, don't try to make eye contact with him.  If you do, he will drive off with the stimulus money.
