Eye halve a spelling chequer;/It came with my pea sea./It plainly marques four my revue;/Miss steaks eye kin knot sea./Eye strike a key and type a word;/And weight four it two say./Weather eye am wrong oar write,/It shows me strait a weigh./As soon as a mist ache is maid,/It nose bee fore two long./And eye can put the error rite,/Its 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 chequer tolled me sew.
