Spell Cheque

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 quay and type a word and weight fore it too 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 won can put the error rite, its rare lea ever wrong.
Eye have run this poem threw it, I'm shore your pleased two no,
Its let her perfect awl the weigh,
My chequer tolled me sew.
