It's been weeks since the article "La Salle Blues" appeared in this column and my e-mail is still drowning with messages exploding with reactions ranging from the angry to the asinine, amusing to the assholic. . . .

To a class that Adams refers to as worker bees, Dilbert and his creator are heroes. Beleaguered workers refer to the abuses inflicted upon them as "being Dilberted."
This verb arises from a grammatical shift of the name of the "Dilbert" comic strip and/or its eponymous main character. The early citations for this new sense only quoted the definition, usually as part of some lame "figuring out geekspeak" article.
