A ox and a mule was workin' together in de same wagon. One day de mule say to de ox, "Look here, Ber Ox, you got to do better, you let me do all de work. If you ain't do better, you guh be kilt, kaze I heared de butcher talkin' to our boss today, and he say, 'Dat ox would make mighty fine beef, I would like to buy him from you.' Ox, if you don't change your ways, you guh be kilt."
And de ox say to de mule, "I ain't guh change my ways for nobody. I'm guh keep on jes like I always been doin', and you jes 'member dis, if I is kilt, my hide will be a terrance to you de balance of your days."
And ever since den mens have been whippin' mules wid ox hides.
