Manhattan Mini Storage ads are always good for a chuckle. For years now, the NYC storage company has taken pride in its cheeky, often topical billboards and mass-transit ads. (You can see a collection of them on its Facebook page.) Now, the spring 2011 ads are out—and what’s this? An execution making fun of the Mets? Those same Mets whose fans comprise a huge portion of MMS’s potential target market? MMS must be counting on Mets fans to have a sense of humor—something that’s not, in my experience, necessarily guaranteed.
