In this Big Mac commercial, McDonald's UK puts random passerby up to the Big Mac Mind Test. Conceived and created by London ad agency Razorfish, the fast food advertisement demonstrates the things people can miss when distracted by the chain's iconic burger.
The Big Mac commercial follows what happens when a couple asks random people walking by to take their picture. In the middle of the ask a giant Big Mac poster goes by, allowing the couple to swap places with a different couple who proceed to have their picture taken. The male speaks the entire time, as if it really were the same couple. The two different sets of people are dressed completely differently and look entirely different as well.
