Dilbert and the Way of the Weasel   (book)

Dilbert and the Way of the Weasel: A Guide to Outwitting Your Boss, Your Coworkers, and the Other Pants-Wearing Ferrets in Your Life

Weaseling on many levels and in many different ways is the topic of this book, from singing weasels who thwart enjoyment of favorite songs by singing along to malevolent manager weasels who shuffle their least competent employees around to "help" with other tasks, thus leaving the best resources for themselves. There is also a helpful discussion about an audio visual gesture to indicate that somebody is being a weasel, in much the same fashion as the "thumb-and-index-finger" loser gesture. Enjoyable reading.
