Not to go off on a tangent, but perhaps a second order Taylor polynomial, at least one version "So Long It's Been Good to Know You" has the following lines:

I went down to the barn, as has been my rule;
Went down to milk, had a pail and a stool.
The cow tossed her head and she swished 'round her tail
And planted her left hind foot smack in the pail.
I said, "Listen here, Bossy, stop pawin' the ground.
I had a hard night, I was slippin' around."
She looked at me with her eyes big and brown
And said "You just hang on, boy, I'll jump up and down.

This looks eerily similar. The verses have the same meter as "Somebody Threw A Tomato At Him" even if the tune isn't quite the same (I found a Johnny Cash recording of "Sweet Betsy from Pike".

I'm inclined to think that there's some sort of connection between these songs, even if it's just that other people besides me have felt compelled to mix and match verses.
