A New Marketing Medium?

Believe it or not, it is called Bumvertising:

[T]he use of sign holding vagrants to advertise, is a development of PokerFaceBook.com's most recent advertising campaign. Homeless men are able to provide a valuable and tangible service to a company, while receiving an additional revenue stream in combination with their normal donations from begging.

How's that for a new wrinkle to "multichannel marketing"? I can't wait for the next version of Adobe InDesign to include an "Export to Vagrant" feature.
