The Elephant's Child (Rudyard Kipling)

I keep six honest serving-men:

  (They taught me all I knew)

Their names are what and where and When

  And How and Why 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--

She keeps ten million serving-men,

  Who get no rest at all!

She sends 'em abroad on her own affairs,

  From the second she opens her eyes--

One million Hows, two million Wheres,

  And seven million Whys!
