Look at this duck. Look at how smooth and fluffy it is. Don't you just want to take it home and snorgle your face in it?
If so, you're not the first. Ladies and gentlefolk, I bring you...the origin of the down pillow
Imagine this: It is winter. You're a primitive fisherperson, living in a little mud hut. You're lying on your straw mat shivering while these cozy little buggers are mucking about by the thousands on a nearby clifftop. One of them strays from the flock and waddles down the beach, combing the rocks for mussels. You reach for your spear. It turns its poofy little head. Too late!
