Tonight I am at an event at Procter & Gamble headquarters in Cincinnati, Ohio, with a group of marketers, agency folks, and other assorted digerati. We’ve been brought together to help the company… sell T-shirts.

You read it correctly. A few weeks ago Advertising Age created a stir by announcing that P&G was bringing together a large group of digital folks for a “Hack Night.” Since then people have speculated about what would come from this event—say, setting new ad-unit standards, figuring out how to monetize video, or maybe even Google, Facebook, and MySpace would face off in a cage match? To add to the mystery, all participants were sworn not to spread a single word of the event. This left many in the digerati world quietly asking each other if they were on the list, and several others were working the phones to get on it.

I’ll share more on the event tomorrow, but right now I need to get back to work selling T-shirts. We have been spread out and broken into four teams with an assignment to sell as many Tide T-shirts as possible before 9 p.m. It’s a great cause and a perfect-fit example of Marketing with Meaning. 100 percent of profits go to victims of natural disaster. Tide has been running the program for years, after starting with a group that traveled to New Orleans to help people wash and dry their clothes in the wake of Hurricane Katrina.

So if you love our cause and purpose, please help out and buy a shirt at www.tide3.com. And remember that if you buy two it’s free shipping and handling!
