Famous quotes containing the words horse and/or tail:
“If this bureau had a prayer for use around horse parks, it would go something like this: Lead us not among bleeding-hearts to whom horses are cute or sweet or adorable, and deliver us from horse-lovers. Amen.... With that established, let’s talk about the death of Seabiscuit the other night. It isn’t mawkish to say, there was a racehorse, a horse that gave race fans as much pleasure as any that ever lived and one that will be remembered as long and as warmly.”
—Walter Wellesley (Red)
“And now he comes again with clatter of stone,
And mounts the wall again with whited eyes
And all his tail that isn’t hair up straight.”
—Robert Frost (1874–1963)
