Duck!

It was a quiet afternoon on the farm, when suddenly... "DUCK!" Duck can clearly see that something is FALLING from the sky. So he tries to warn Horse... "DUCK!" he cries. Horse snorts. "Duck? No, no! You're mistaken my friend. You are a duck. I am a horse. I look nothing like a-" But, before Horse can finish, Duck is off to warn the others. "DUCK!" But, no matter how loud Duck shouts, not one animal on the farm will listen to him - not the horse, or the sheep, or the pig, or the cow! Just what will happen when that falling something finally reaches the ground?
