My great grandpa sang this version to his kids and my grandma sang it to me:

There was a man, named Osenwald
He bought a goat, it was last fall.
He bought this goat, but not for fun
He bought it for his only son.

He took him home one afternoon,
It was a sunny day in June.
He tied him down to the clothesline,
There hung six shirts, Billy said I'll dine.

When Osenwald saw what Billy had done,
He said prepare, you son of a gun.
He took him down to the railroad tracks,
He tied him down, then he turned his back.

When Billy saw the approaching train,
He coughed and he coughed, but it was in vain.
And then he gave a terrible strain,
Coughed up the shirts, flagged down the train
