The man on the street.

I would love to have seen the client presentation for this Vonage campaign. "Yeah, our concept is to have as a spokesman a dirty, smelly street person.. You know snarly hair, that probably has lice, mismatched clothing that doesn't quite fit, a half-hearted tie.  Someone who looks homeless and a little demented. He'd talk about the Vonage coverage, but at the same time he would look like he couldn't afford to have a phone of his own, or know anybody he could call. We think that's the image that Vonage should go for."
