David Perez, a creative recruiter at the Chicago-based Leo Burnett advertising agency, says he convinced his boss to send him to the Cannes Lions International Advertising Festival this week - but there was a big condition.
From today, anyone on the internet can log into David Perez's twitter account and order him to do whatever they like.
As long as the deed is legal, Perez promises to do it.
"Everything I do, you control. Tell me to go jump in the fountain at the [Hotel] Martinez, and I'll do it," he said in a video explaining the project.
"I'm your slave. I'll do whatever you tell me to. Please be gentle."
So people don't have to take his word for it, Perez has mounted a small webcam to his glasses.
"Everything I see while I'm in Cannes, you'll see," he said.
On the David on Demand twitter feed, he tweeted: "Part of me is excited to share the Cannes experience. Part of me is excited to be on demand. Part of me thinks that second part is an idiot."
Perez told Forbes.com that David on Demand was part of the promotional effort for Leo Burnett's "Wildfire: The Here & Now/Spontaneity in Modern Marketing" seminar.
The seminar is about connecting with consumers in real time, and the people at Leo Burnett decided they wanted to show that spontaneity rather than just talk about it.
"It's a great way for us to explore this new technology and how social media is the future of our industry," Perez said.
To send Perez a demand, go to http://twitter.com/davidondemand starting 7pm (NZT) today.
