In the Piccadilly Circus photo shot during my personal student days traveling Europe are two punks with incredible mohawks and a double decker bus in the background. A McDonald's billboard on Piccadilly Circus would have been cause for "industrial action" on the part of the Brits and monkey-wrenching by touring students.
But billboards are funnier these days, and teh young take advertising as part of life. And as for me, I just passed along a viral ad for McDonald's. We're all just servants of Big Burger.
