Spell Checker Humor

I halve a spelling checker,
It came with my pea see,
It plainly marks four my revue,
Mistakes I dew 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 aweigh.

As soon as a mist ache is maid,
It nose bee fore two long,
And eye can put the era rite,
Its rarely ever wrong.

I've scent this massage threw it,
And I'm shore your pleased too no,
Its letter perfect in every weigh;
My checker tolled me sew.
