When I was just a wee little lad
Full of health and joy
My father homeward came one night
And gave to me a toy
A wonder to behold it was
With many colors bright
And the moment I laid eyes on it
It became my heart's delight

[Refrain:]
It went "Zip" when it moved and "Pop" when it stopped
"Whirrr" when it stood still
I never knew just what it was and I guess I never will

The first time that I picked it up
I had a big surprise
Cause right on the bottom were two big buttons
That looked like big green eyes
I first pushed one and then the other
Then I twisted its lid
And when I set it down again, here is what it did:

[Refrain]

It first marched left, and then marched right
And then marched under a chair
And when I looked where it had gone
It wasn't even there
I started to cry, but my daddy laughed
'Cause he knew that I would find
When I turned around my marvelous toy
Would be chugging from behind
[Refrain]

The years have gone by too quickly it seems
I have my own little boy
And yesterday I gave to him
My marvelous little toy:
His eyes nearly popped right out of his head
And he gave a squeal of glee!
Neither one of us knows just what it is
But he loves it just like me!

But still it goes "Zip" when it moved and "Pop" when it stopped
"Whirrr" when it stood still
I never knew just what it was and I guess I never will
