For what it's worth, I found this at http://users.erols.com/wwcassoc/APR00WHATALL.htm:IT'S BEEN SAID: Silly North Carolina country ditty from the early 1900s.
From our 93 yr old friend Johnny Winstead. His Uncle Gideon ("Giddy") taught it to him. It's about "The old cow": "The old cow died with a rag in its mouth. The rag blew out. The wind blew in. And the old cow came to life again." Johnny says Uncle Gideon "had about as big a handlebar mustache as you ever saw."
