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.
