Will the zebra run through fire?

I heard the story that when there is a fire on the serengetti plains, most of the animals will run away from the flames until they are exhausted and will be overcome by the flames and smoke. The zebras - at some point their instinccts kick in and the herd will stop running, turn and watch the flames coming closer - then they will bolt forward and run back through the flames. They will get singed, but will be otherwise unharmed. Whether this is fact or fiction - it makes a wonderful story. I have shared the story with others when life seems to be overwhelming for them....then we have a common language and they remind themselves to "run back through the fire!"
