I keep six honest serving men
(They taught me all I knew);
Their names are What and Why and When
And How and Where and Who.
I send them over land and sea,
I send them east and west;
But after they have worked for me,
I give them all a rest.

I let them rest from nine till five,
For I am busy then,
As well as breakfast, lunch, and tea,
For they are hungry men:
But different folk have different views:
I know a person small--
He keeps ten million serving men,
Who get no rest at all!
He sends 'em abroad on his own affairs,
From the second he opens his eyes--
One million Hows, two million Wheres,
And seven million Whys!

(Rudyard Kipling, Just So Stories)
