From the Wikipedia "Hedgehog" entry:

"In 2006, McDonald's changed the design of their McFlurry containers to be more hedgehog-friendly.[9] 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."

"Observe Everything. Always think for yourself. Never let other people make important decisions for you." — from Bad News by Edward St. Aubyn
