A farmer went each week to the Farmers' Market to sell, among other things, the cottage cheese and apple butter made on his farm. He carried these in two large tubs, from which he ladled the cottage cheese or apple butter into smaller containers the customer brought. One day he got to market and discovered he's forgotten one ladle. He felt he had no choice but to use the one he had for both products. Before long he couldn't tell which was which.
