Yesterday, as part of an ongoing practical joke war, a friend sent me an invoice via PayPal. He then e-mailed me and said that if I didn't pay, he would, "turn on the juice, 2 1/2 points per day".

That got me thinking about a great new revenue source for PayPal, loan sharks. They could invoice their 'clients' and then automatically charge interest (or juice as we call it on the streets). Of course PayPal would take their standard percentage off the top.

Here is a mock-up of the promo offer you'd see when you visited your PayPal account.

Then again, maybe loan sharks don't want too much documentation of their business dealings :-)
