When I was little, I used to watch "A Christmas Story" every holiday season with my parents. There's a scene in the movie where the main character gets punished for saying "Oh, fudge!" and so for years I thought "fudge" literally WAS the F-word. I remember telling one of my neighbors, "Isn't it weird how the worst cuss word in the world is a dessert?" I didn't understand the confused look he gave me until much later.
