Signals: Dilbert 2.0 - 20 Years of Dilbert by Scott Adams
Long before "The Office" appeared on the scene, Scott Adams delivered Dilbert unto a wearing working world. And we have never looked at our bosses quite the same way again. This 600-page compendium was carefully edited by Adams himself and includes his first cartooning check, his own asides and a disc with every Dilbert strip thus far created. Good gifting.
