I'm My Own Grandpa

I'm My Own Grandpa (sometimes titled as I'm My Own Grandpaw) is a novelty song from 1947. It has been covered by many artists who do humorous songs, among them the well-known American recording artist Ray Stevens. The song's origin is a short piece written by Mark Twain in 1883.

It is a humorous tale of two totally legal marriages: the first involving the narrator who marries a widow, and the second when the widow's daughter marries the narrator's father. Although the song continues to mention that both couples had children of their own, the two initial marriages produce the song's title (by, of course, conveniently leaving out the "step" portion of each):

• When the narrator married the widow, her daughter became his stepdaughter.
• Then when the narrator's father married the widow's daughter, because she is now his father's wife, the daughter is now also his stepmother. (This also makes his father his stepson-in-law as well).
• The narrator's wife, being the mother of his stepmother, is now his step-grandmother.
• This would make the husband of the narrator's wife his step-grandfather. As he is that person, he has become his own (step-) grandfather.
