Remember Danny from "The Apprentice"? The guy who composed funky advertising jingles while playing on his guitar? At the Digital Marketing Conference & Expo in New York, he was a featured speaker on the art of selling air:

"Mr. Kastner's presentation, "Selling Air: A Real-time 'Mocumentary,'" will present a cohesive e-marketing strategy for fictitious client SkyAwry Inc. in its effort to sell its newly-patented innovation: air! Much like "The Apprentice," this lively session will start off with a bang when a SkyAwry marketing project manager is accused of incompetence, resulting in her firing in the company boardroom. Mr. Kastner will then engage the audience to help develop a fresh cutting edge approach- using the latest in digital technology- to bring the vaporous product to market."
