"In 2006, McDonald's changed the design of their McFlurry containers to be more hedgehog-friendly. Previously, hedgehogs would get their heads stuck in the container as they tried to lick the remaining food from inside the cup. Then, being unable to get out, they would starve to death."
We found this quote in Wikipedia, when we were looking up information about hedgehogs. How many hedgehog's walk into McDonald's? It was awfully nice of McD's to think of the little spiny fellows.
