Some of the readers’ comments following my recent article of Is There Any Such Thing as a Half-Cousin? at http://goo.gl/j4y3q1 described some complex relationships. The comments include stories of “double first cousins,” children who are simultaneously siblings as well as cousins, and more. All of this reminds me of a popular song from the 1940s called “I’m My Own Grandpa.”
The song was written by Dwight Latham and Moe Jaffe, performed by Lonzo and Oscar in 1947, about a man who, through an unlikely (but legal) combination of marriages, becomes stepfather to his own stepmother. The song pays no attention to the prefix “step-” however. As a result, the singer becomes his own grandfather.
