McDonald's Receives Calls About 'Falling' Billboard

So Arnold created a billboard for McDonald's to promote the restaurant's new banana bread. The billboard shows an image of the bread with a cut slice affixed to a portion of the board that, itself, looks cut off from the rest of the board. It's an effective use of a billboard extension.

But, more interestingly, passersby are calling McDonald's to inform them the billboard is falling down. Apparently, they don't know what a billboard extension is. Oh well. Anything for publicity, right?
