Diet Pepsi Max - Big Yawn
Summary: People in an office start to yawn in harmony, then it spreads all over the city.
An office worker on the phone starts it all with an innocent yawn. Then his co-workers all around him start yawning too. It is said that yawning is contagious, but this ad takes it to a new level.
Outside the office, via the shipping guy, people on the street start yawning. The yawn takes a ride on a bus and perpetuates all over town.
At an election campaign rally, a photo op is ruined when the candidate starts yawning. He's being broadcast on television, which leads back to the original office, where people are still yawning. The first guy who started it is now drinking a can of Diet Pepsi Max, and gets a boost of energy, spinning around in his chair.
