When I was a child, I used to believe babies were born in cabbages. Once my mother brought a cabbage home and I was scared she would cut it and kill the baby, so I used a pen to try to dig a tiny hole in it to see the baby...
No need to say the cabbage was ruined.
I didn't get punished though, for my mother thought it was cute. But she did explain that babies were NOT born in cabbages... I remained doubtfull for a long time.
