Take Will It Blend? and the hundred-dollar cheesesteak at Barclay Prime. Both stories evoke emotions like surprise or amazement: Who would have thought a blender could tear through an iPhone, or that a cheesesteak would cost anywhere near a hundred dollars? Both stories are also pretty remarkable, so they make the teller look cool for passing them on. And both offer useful information: it’s always helpful to know about products that work well or restaurants that have great food.
