There are so many verses it's hard to know which ones were never in the original. For instance, my favorite verse may have been taken from Whoa Mule:
"Granpa had an old grey mule,
Rode him into town,
'For he got his shopping done
The buzzards had him down."

I wonder what the author was thinking when he wrote,...One night I saw a big fat coon climb up in a tree,
I called old Rattler right away to get him down for me.

That's silly. The dog trees the coon, no way can he "get him down".
