Hello, I am a librarian in the San Diego, California area with a patron who would like a confirmation on a supposed Mark Twain anecdote entitled: "I am My Own Grandfather". There is a humorous song by Dwight B. Latham and Moe Jaffe called "I am My Own Grandpa" (c.1947) that was supposedly based on the reading of the Twain anecdote in a book. I have searched the Twain-L archives. Also, I have searched in roughly 24 books here at the research library (all listed on the bibliography in the Twain-L "Survival Guide"). The only one I do not have access to that looked like it might be useful is: Rasmussen, R. Kent (ed.). _The Quotable Mark Twain: His Essential Aphorisms, Witticisms and Concise Opinions_. Chicago: Contemporary Books, 1998. I can't find reference to this particular anecdote. "His Grandfather's Old Ram" and "What Paul Bourget Thinks of Us" were the only two stories I could find with a grandfather connection. Would there be any information to give my patron to prove or disprove the existence of this anecdote in a Twain source? I thank you in advance for information and attention to this query.
