A childhood belief about nasty food

When we were kids, my mother, in order to make us 3 kids behave, told us that if we were bad in public we would be sent to the "cookie house". My belief was that there was this strange little house that bad kids went to live if they misbehaved. This was a horrible little place where kids were given nothing but rock hard black cookies to eat. I even went as far as to believe that the "cookie house" was a small shed that stood in a park in my hometown (the shed was made into a "Santa House" at Christmas - so I thought that all the bad kids were moved only at Christmas time). Strange how this story scared us enough to make us all behave while out with mom!
