I have a very early Peggy Seeger record - one of the earliest 1950s vinyl 33s - which includes a "Children's medley""; one little bit of which goes

Jawbone walk and jawbone talk
Jawbone eat with a knife and fork
I left my jawbone at the corner of the fence
And I have not seen my jawbone since

I have always regarded that as simply a bit of somewhat puzzling nonsense verse (which indeed it is: what means "jawbone"!?). But now I can at least see, from above bits about the wife's jawbone being sent to the narrator, whence it has floated as a sort of corrupt discrete fragment.
