Big Mac Turns Your Brain Into a Drooling Pile of Oblivious Mush in British Ad Stunt

McDonald's plays mind games

McDonald's puts our minds to the test in this British campaign from Razorfish that features prankvertising and an online quiz.

The premise is that people can't concentrate on anything else when the Big Mac is nearby. Unlike some recent hair-raising ad stunts, and the million-calorie sandwich itself, the prank element here is pretty benign.

On a busy street, a young couple with a camera ask presumably unsuspecting passersby to take their picture. As they primp, a large portrait of a Big Mac is carried past by a different couple, who quickly switch places with the original pair just as the photo is about to be snapped. (It's cool how boyfriend No. 1 starts a sentence as the Big Mac obscures him from view, then boyfriend No. 2 appears and completes the sentence once the switch is made.)

The subjects don't seem to notice that anything's amiss. Maybe a devil baby puking up special sauce would've gotten their attention? Just a thought.

Anyway, the original couple from the clip also host a series of interactive "mind games" designed to demonstrate the Big Mac's distracting power. I thought the hypnotic properties of two all beef patties, yada yada, on a sesame seed bun had been irrefutably established long ago. Obviously, when one appears, so plump and juicy … I cannot turn away!

Oddly, when McD's showed in detail how McNuggets were made, I couldn't make the screen go dark fast enough. Still, I'll have fries with that!
