I have a spelling checker - 
It came with my PC. 
It plane lee marks four my revue 
Miss steaks aye can knot sea.

Eye ran this poem threw it, 
Your sure reel glad two no. 
Its vary polished in it's weigh, 
My checker tolled me sew.

A checker is a bless sing, 
It freeze yew lodes of thyme. 
It helps me right awl stiles two reed, 
And aides me when aye rime.

To rite with care is quite a feet 
Of witch won should be proud. 
And wee mussed dew the best wee can, 
Sew flaws are knot aloud.

Each frays come posed up on my screen 
Eye trussed to bee a joule 
The checker poured o'er every word 
To cheque sum spelling rule.

That's why aye brake in two averse 
By righting wants too pleas. 
Sow now ewe sea why aye dew prays 
Such soft wear for pea seas
