A childhood belief about work

This is a story that my mother tells - it happened to my cousin when he was 5. Once day my cousin came down to visit his auntie and uncle (my parents). He asked my father what he did in the day. At the time he worked at an oil refinery, but decided that the process of refining hydrocarbons was too difficult for a child to understand. Instead he told him that he worked at a rabbit factory, and pointed out the window to one of the tall stacks at the refinery - telling my cousin that he stood up on a metal tower and counted the rabbits in the fields below to make sure none ran away. My cousin believed this for a further two decades, and even now (at the age of forty) he still goes bright red when its brought up!
