A man was married to a wife with a particular aversion to cooking. Everyday, all day, she sat around the house eating bonbons and watching 'As The World Churns on TV. When he came home after a hard day at work and asked, "What's for dinner, Hon?"
She always replied, "How do I know. Fix what you want."
So, getting tired of this and wanting some nourishing food, he invented an electric pot he could turn on, leave it all day, and have a delicious roast or tasty stew in the evenings.
After talking to his fellow workers about this, they wanted one just like his. Realizing he had something good, he tried to sell it to a local manufacturer. The manufacturer told him, "I think that's a lot of of crock."
