Hundreds of French citizens lost their cool last week, driven to desperation by a grocery chain's sudden 70% price drop for a jar of Nutella. Stories of "Nutella riots" began to spread; videos showed crowds of people shoving and yelling in supermarkets, trying to reach the jars. In at least three cases, police were called after customers came to blows in the frenzy for Nutella, according to a French newspaper, “Le Parisien.”
