At the book store, I was looking for some guide to enhance my English and I came across a small one which looked moderately helpful. And it was affordable. Problem : the author says he wants to teach English by joking. It is not bad in itself to bring in some humor into teaching, but as I peered into the book, I realized that the jokes were distasteful, focussing on sexual and base activities and language, nothing too refined. In addition, it makes use of quotes of contemporary series and movies. It’s not a bad idea, but since I hate almost all series, I was not happy. And the jokes were not very funny, they were even annoying. You know when some uncool guy wants so much to be funny that he ends up being the opposite and people around find him unbearable. So I left the book behind and I spared my money.
