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 write.
Its rare lea ever wrong.

Eye half run this poem threw it,
I am shore your pleased two no
Its letter perfect awl the weigh.
My chequer tolled me sew.
