There are only two things To worry about:

Either you are well
Or you are sick.

If you are well,
Then there is nothing to worry about.

But if you are sick,
There are two things to worry about:

Either you will get well
Or you will die.

If you get well,
Then there is nothing to worry about.

But if you die,
There are two things to worry about:

Either you will go to heaven
Or you will go down there.

If you go to heaven,
Then you have nothing to worry about.

But if you go down there,
You'll be so darn busy shaking hands
With all your friends,
That you won't have time to worry!
