Eye strike a key and type a word End weight four it two say Weather eye am wrong our write – It shows me straight a weigh. As soon as a mist ache is maid It nose bee fore two long, And eye kin put the arrow rite It’s rare lea ever wrong. Eye have run this poem threw it; I am shore your pleased two no Its letter perfect awl the weigh, My spell chequer tolled me sew!
