Author's Comment: My publishers phoned me up and said, ‘Would you like to write a history joke book?’ I said, ‘I don’t know anything about history.’ They said, ‘Don’t worry about that. We’ll give you the facts, all you have to do is write the jokes to go with them.’“So I started off, but I soon found the facts much more interesting than I’d expected. By the end instead of having a joke book with facts, we had a fact book with jokes. I seemed to have invented a new genre.
