or perhaps of the decade for those of us with small kids -- Kipling's Six Honest Serving Men

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 --
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!
