Here is the song that my grandfather born in 1888 in western Pa. used to sing to me as a child and this was his version of the song.

I had a horse who's name was Napoleon
All on account of his bony parts
I hitched him up to an old milk wagon
and when you'd holler "milk" he stop that cart

As I was going down the street
when a friend I chanced to meet
So he said to me-"now look here Silas
let's have a race right down the street"

So off we started helter skelter
Me with a grin all over my face
You can bet your dinner I was coming in a winner
when a women hollered "MILK" and I lost that race!
