I listened to the Carter Family song again. Between each of the verses I gave there is a chorus:

Chewin' chawin' gum
chawin' chewin' gum

This makes it a more self-contained song without the other verses.

Speaking of grossing out: There is an old parody on the popular song Jealousy called "Leprosy". I (happily) don't remember much of it--just one verse.

Leprosy, I suffer from leprosy
There goes my eyeball into my highball

but the rest isn't any better.
