I bought this having read the "sequel", What Not to Do (And How to Do It). That was a book that had been left by the pool on my holiday, and having picked up the sundried, glue-failed book (minus the first 25 pages which had come unstuck and disappeared), found I couldn't put it back down.
This earlier book is much the same. Made up of small anecdotal stories, Danny Wallace intentionally comes across as a naive, dopey, geeky social misfit. I think what that achieves is to nail those awkward moments most men find themselves in at some point in their lives perfectly, amplifies them, and concentrates them into a book. The fact that he comes up with such funny stories shows that in fact he's anything but stupid - clearly he is very intelligent. So you don't know how true the stories are, but it feels like they're based on real events, and simply well embellished.
The fact is, you don't mind that one iota, because while each story's conclusion becomes almost predictable, they are still unique, and what really makes you laugh out loud is not necessarily the final punchline of each story, but all the golden nugget lines that you find interspersed throughout. And I can tell you, both this and the sequel had me laugh out loud on numerous occasions.
Some stories are definitely better than others, and at one point, about quarter of the way in, it felt as though they were deteriorating into a bit-too-silly territory. But thankfully it bounced back and in the main, most of the book is very, very good - and the sequel even better.
Well worth getting for your holiday.
