Once when I was little, I heard someone referring to "Cabbage Patch Babies" (as in the toy doll). I took this to mean that babies came from cabbages. You went and got one from the grocery store and took it home. When you had waited long enough, the cabbage would grow into a baby.
Imagine my horror when I walked into the kitchen one day and found my mother cutting up a cabbage to make cole slaw!
I started screaming that she was "killing the baby". It took her like an hour to calm me down so she could figure out why I was so upset!
