Then there's always the wonderful talking blues made popular in the UK, at least, by Lonnie Donegan: "Talking Guitar Blues"

"Bought me a gitar 'bout a year ago,
Man said ah c'ld larn it in a week or so,
Gave me a book, a pick or two,
Said 'There y'are boy, now it's up ta you!'
(dirty rat...)"

Still in my open mic repertoire fifty years or so later. Still gets laughs, too!
