The fine print on the Derrie-Air ads at Philly.com discloses this is "a fictitious advertising campaign created by Philadelphia Media Holdings to test the results of advertising in our print and online products and to stimulate discussion on a timely environmental topic of interest to all citizens. ...In other words, smile, we're pulling your leg." There are at least 18 fake ads -- without the disclosure -- in today's Inquirer and Daily News print editions.
