After selling out of its first run, the book settled at number 744 on Amazon’s best seller charts. That’s good enough to beat perrenial favorites like Dan Brown’s The Da Vinci Code (2,910) and JK Rowling’s Harry Potter and the Order of the Phoenix (2,406).
The book has taken off in the UK, where young men have given the book as a gag gift to friends. Those friends have begun to use the book as a place to keep lecture notes.
“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,” he told the Daily Mail.
Simove said the book took 9 days from the date of conception to publication to finish.
