I'm My Own Grandpa
1947 SONG PERFORMED BY GUY LOMBARDO
I'm my Own Grandpa; I'm my own Grandpa; I'm my own grandpaw; I'm my own granpaw; I'm My Own Grandpaw
"I'm My Own Grandpa" (sometimes rendered as "I'm My Own Grandpaw") 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 (but legal) combination of marriages, becomes stepfather to his own stepmother—that is, tacitly dropping the "step-" modifiers, he becomes his own grandfather.
