Just in case, you get it wrong......

An older gentleman was 
On the operating table.

Awaiting surgery
And he insisted that his son,
A renowned surgeon,
Perform the operation.
As he was about to get the anesthesia,
He asked to speak to his son
'Yes, Dad, what is it? '

'Don't be nervous, son;
Do your best
And just remember,
If it doesn't go well,
If something happens to me,
Your mother
Is going to come and
Live with you and your wife....'
