My sister and I used to watch the Bugs Bunny cartoons on Saturday mornings. There's the one where Bugs is singing Jimmy Cracked Corn. We thought he was singing Jimmy Crapped Corn,which made total sense to us. We found out later in school what the real words were, it still made more sense to us that Jimmy would be crapping corn instead of cracking it and we grew up on a farm. It's a lot more comical to. I still sing the song that way.
