As noted in this reviewer's piece on How I Met Your Mother's 100th episode, one of the best elements of the series is Neil Patrick Harris' Barney Stinson. Harris has made a potentially highly unlikable character into the breakout one on the series. Since the show's inception Barney has maintained a blog on the CBS website. The blog has been used as an extension of the series, with entries building off of plotlines and jokes within the show. The blog perfectly suits Barney and his personality, offering both kernels of wisdom and bits of true insanity.
Barney Stinson's writing does not however begin and end with his blog. No, with the help of Matt Kuhn, in 2008 Stinson published his first book (that we know of), The Bro Code. That title explained in great detail what it means to be a "Bro." Now, building off of that title, Stinson and Kuhn have released the nearly-pocket-sized book, Bro on the Go, which features "new wisdom and select classics from The Bro Code for today's active Bro."
This new title is divided into chapters such as "A Bro at the Ballet," "A Bro at the Mall," and "A Bro at the Bar," so as to provide the reader with easy access to advice for whatever predicament they may find themselves in. Within each chapter Stinson provides short (no more than three or four sentences) pearls of wisdom about a Bro's proper actions in the various situations. For instance, in the mall chapter, Stinson offers the advice that "Lingering around the children's play area to scope out the hot young moms is a good idea in theory only."
One should not think that Stinson's entire thoughts as they relate to the Code are purely sexual (though those are the majority). Stinson instead extends his thoughts to other general man areas such as in the "A Bro Behind the Wheel" chapter where he cribs from The Bro Code stating "A Bro never admits he can't drive stick. Even after an accident."
