It taught a couple of generations of city folks that turkeys are flightless birds.
See, the thing is, turkeys can fly. That's why the domestic ones get their wing feathers clipped, I suppose--I don't know. All I know is that I can take you out to the woods and sit you down under a tree where turkeys are roosted, and when dawn comes, you'll see them fly down.
They're not always graceful, and they make an awful racket, but I promise you that turkeys can fly.
