While Shepherds Washed their Socks by Night

There’s two ways to round up sheep, it seems. You can get yourself a border collie puppy from a long line of champion sheepdogs, train it up until it obeys your slightest command, and trek out with it to a remote hilltop and stand whistling complicated instructions until the sheep are safely gathered in.

OR

You can just drive to the edge of the field, honk your horn a few times and watch the sheep come running. I’m guessing the latter approach involves tasty sheep treats (erm, grass?) and sheep that haven’t worked out where the last batch of lambs went to.
