Farmer Ned bought a pasture surrounded by a beautiful wooden fence. He built a dividing fence and moved his horses to one end and his cows to the other. But the next day, most of his new neighbors called to report animals in their yards. It turns out the fences were not as sturdy as he thought.
Ned repairs the fence, but the next day his neighbors call again. There are horses in Dan's yard and cows in Tim's.
Again Ned fixes the fence but the next day, Dan reports cows and horses trampling his garden.
Ned drives the animals back, but doesn't have time to do much for the fence. Sure enough, the phone rings the next morning. Gus, his neighbor to the north, reports horses in his yard. Lisa, his neighbor to the south, reports cows in her yard, and Dan is on the phone as well.
Ned fixes the fences, but the following day there are horses in Tim's lawn and cows in Dan's.
Grumpily, Ned surrounds the property with a steel wall. This mostly works, but the horses jump over it to visit Tim.
Ned makes that part of the wall higher, but the horses just escape out the opposite side. Meanwhile, the cows have escaped to visit Dan and Lisa.
Ned makes the wall higher and for good measure, electrifies it. The next morning his phone is silent. No animals have escaped!
That night he goes to sleep feeling content. But the next morning, the phone rings. Who is it?
