This song was in an old songbook we used for elementary school music class in the mid - late 1960s. I remember one verse was

I got on the Dummy and I didn't have my fare
The conductor hollered, "What ya doin' there?"
I got up and I made for the door
But he cracked me on the head with a two by four

On the Dummy....

Like I said, this was in a hardcover songbook (the music teacher would stack on top of the piano and then push the piano from classroom to classroom,), so this verse has to be in a published version of the song.
