Mr Simove, 39, an Oxford University graduate who is an author, performer and entrepreneur, added: “I never anticipated that my book would be used for students to take their lecture notes in. In a sense they are proving me wrong by filling my book with content. But I wonder how many of them go back to thinking about sex once the lecture is over. I’d be willing to bet that answer is 100%. In fact I would go even further and estimate that 99% are thinking about sex even during the lecture. They probably think using my book as a notepad will help them get laid. And they are of course totally correct in that hypothesis.
