This is ridiculously short. In fact, I read it in about 5-10 minutes in the books department while I was waiting for my parents to finish up with their shopping, but it was probably one of the best times I've spent while waiting for someone, ever. It's definitely an amusing read, especially for 'How I Met Your Mother', Neil Patrick Harris, and Barney Stinson fans.
So why the 3 star rating? Well, like I said, it's so short! I know that the whole point of this book is that it's supposed to be small enough for someone to slip into their pocket, but it really felt like more of a 'best-of' from the Bro-Code, rather than a miniaturized dictionary-style version that I was expecting. (Although, now that I've read this, I will most likely pick up the Bro-Code for real. :P).
Also, for being a self-help book for someone 'on the go', it seemed to lack a most definite need for a TOC in the front. It did have an index in the back, but otherwise, I really can't judge this book too harshly past that. It gave me a good laugh while I was waiting, and that's probably more than what I could've asked for.
