There was a farmer who had a balky mule and he couldn't make the mule
go. A stranger came along and offered to help, and the farmer told him
to go right ahead. The stranger had a bottle of turpentine, and he
opened the mule's mouth and pushed back his head and poured about half
of the bottle into the mule's stomach. The mule gave one startled gasp
and struck out across the prairie, and was lost to sight. The surprised
farmer stood for a while immersed in deep thought, and then he said,
"Stranger, please give me the rest of that turpentine; I've got to catch
my mule."
