Quick n dirty:

When the stocks come tumbling down
There's pain and sorrow all around
But there are some who like this better:
This is a job for the short seller.
Off they go all bold and brash
To sell stuff they don't have for cash
And doing so they start the slide
They're banking on - now that's some ride.


The fact is that what we're experiencing right now is a top-down disaster. -Paul Krugman
