Your Tuesday Spell Checker

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 prefect in every weigh; 
My checker tolled me sew.
