“I’m My Own Grandpa” is a novelty song written by Dwight Latham and Moe Jaffe, performed by Lonzo and Oscar in 1947, about a man who, through an unlikely combination of marriages, becomes stepfather to his own stepmother—that is, tacitly dropping the “step-” modifiers, he becomes his own grandfather. For the 1987 album “Crackin’ Up”, Ray Stevens recorded his own version of the classic comedy song “I’m My Own Grandpa”. In the 1930s, Latham had a group, the Jesters, on network radio; their specialties were bits of spoken humor and novelty songs. While reading a book of Mark Twain anecdotes, he once found a paragraph in which Twain proved it would be possible for a man to become his own grandfather. (“Very Closely Related” appears on page 87 of Wit and Humor of the Age, which was co-authored by Mark Twain in 1883.) In 1947, Latham and Jaffe expanded the idea into a song, which became a hit for Lonzo and Oscar.
