Sometimes when you're feeling important,
Sometimes when your ego's in bloom,
Sometimes when you take it for granted
You're the best qualified in the room,
Sometimes when you feel that your going
Would leave an infallible hole,
Just follow these simple instructions
And see how if humbles your soul.
Take a bucket and fill it with water.
Put your hand in it up to the wrist,
Pull it out and the hole that's remaining
Is the measure of you you'll be missed.
You may splash all you wish when you enter,
You can stir up the water galore,
But stop and you'll find in a minute
It looks quite the same as before.
The moral of this quaint example
Is to do just the best you can
Be proud of yourself, but remember,
THERE IS NO INDISPENSABLE MAN.
