Leading the way, this pocket guide should not take all too seriously. It leans partly on "How I Met Your Mother", but much is still new for fans of the series. You should bring good English skills, because many articles were written colloquially.
Otherwise I am the öffteren good time. One reads the styles of Barney Stinson out clearly.
The only drawback I had with the book in 2 days. And I did not even read intensive. Yet every Barney fan should daily at least once.
