Laser Corneal Ablation

Who and when, where and why,
What does the pain of life imply?
Almost as blue as God's blue eye,
Aim your lasers at the sky,
And with a ringing battle cry
Sharpen the vision of the big old guy.
Me oh me, my oh my,
That should straighten out Captain Bligh;
He'll be as soft as a Windsor tie,
And give us candy and rhubarb pie.
