According to legend, animals observe Christmas with their own customs. Out of respect for the Savior's birth sheep walk in procession, bees hum a Christmas carol, roosters crow all night, and, for one hour on Christmas Eve, all animals can speak. It it's bad luck to test these things.
Here's what the Animals actually say on Christmas Eve
"Whosoever on the night of the nativity of young Lord Jesus in great snows shall fare forth bearing a succulent bone for the lost and lamenting hound, a wisp of hay for the shivering horse, a cloak of warm raiment for the stranded wayfarer, a flagon of red wine for him whose marrow withers, a garland of bright berries for one who has worn chains, gay arias of lute and harp for all huddled birds who thought that song was dead and divers lush sweetmeats for such babes' faces as peer form lonely windows - To him shall be proffered and returned gifts of such an astonishment as will rival the hues of a peacock and the harmonies of heaven, so that though he live to great age when man goes stooping yet shall he walk upright and remembering, as one whose heart shines like a great star within his breast." -Anonymous
