Weightwatchers has a very creative marketing team. In this ad they put a huge sticker on the back of a public bus. The bus is leaning to the right because someone with too much weight is sitting on the rightside. They want to motivatie people that are to heavy to join weight watchers.
Allianz is an insurance company. Dental insurance is a difficult product to market because it is a necessary evil. You rather not think about it. Allianz used humor to inform their potential customers about the Allianz dental insurance. When people have bought a train ticket whit out a date they use a machine to put a date on the ticket. When you put your ticket in the machine it looks like the guy is biting in the ticket.
Never stop biting.
