bizwriter writes: General Motors put together its take on a George Carlin list of words you can't say. Engineering employees were shown 69 words and phrases that were not to be used in emails, presentations, or memos. They include: defect, defective, safety, safety related, dangerous, bad, and critical. You know, words that the average person, in the context of the millions of cars that GM has recalled, might understand as indicative of underlying problems at the company. Oh, terribly sorry, "problem" was on the list as well.
