Farmer Hobenstein has 24 cows, all of which never move at all. They are arranged on four sides of his rectangular house, 6 on each side, and there are windows through which he can watch them. He never goes out there, though.
One night the notorious Bellatrix Lestrange stole 12 of his cows. But still, Hobenstein could still see 6 cows on all four sides for ages.
