Way back when, in days of yore, Alex Tourk and Gavin Newsom were friends and worked on projects together, like San Francisco Connect. And so they decided to that in order to get people to join in and volunteer, they needed to come up with an advertising campaign. Which they did. And guess what tag line they came up with for Project Connect? "Volunteering is Sexy."

Guess what new advertising campaign is going live this week?

Yep, you guessed it.

So many punch lines, so little time. So how's this: "It's so sexy you'll forget your boss is having sex with your wife, while you help homeless people set up voicemail."
