A mean & nasty horse fly bit my pony Marley on the face and made him bleed. If I'd been there I would have pounded that fly into the ground without first putting a point on its head.
Despite the vile attack, Marley is still the more noble creature.
"A fly, Sir, may sting a stately horse and make him wince; but, one is but an insect, and the other is a horse still."
--- Samuel Johnson
Not all horse flies are bad however. We dig the groovy hoof stompin' sound of The Horse Flies below.
