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

It went 'Zip' when it moved, 'Bop' when it stopped
'Whirr' 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
For right on its bottom were two big buttons that
Looked like big green eyes
I first pushed one and then the other and then I twisted its lid
And when I set it down again, this is what it did

It went 'Zip' when it moved, 'Bop' when it stopped
'Whirr' when it stood still
I never knew just what it was
And I guess I never will

It first marched left and then marched right
And then marched under a chair
And when l looked where it had gone, it wasn't even there
I started to sob and my daddy laughed
For he knew that I would find
When l turned around, my marvelous toy
Chugging from behind

It went 'Zip' when it moved, 'Bop' when it stopped
'Whirr' when it stood still
I never knew just what it was
And I guess I never will

Well, 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

It went 'Zip' when it moved, 'Bop' when it stopped
'Whirr' when it stood still
I never knew just what it was
And I guess I never will
I never knew just what it was
And I guess I never will
