One of your elementary school teachers probably once told you that there's no such thing as a stupid question. Like so many lessons imparted by elementary school teachers, this is a fatuity and a hoax. There are indisputably such things as stupid questions. In fact, there are so many stupid questions out there that the mere descriptor "stupid question" is not nearly specific enough. After years of careful study and documentation (often at substantial risk to my mental health) I am here to present what is, to my knowledge, the first complete taxonomy of stupid questions of the North American Retail bioregion:
This question importunes the questionee for information that it is not within said individual's job description to provide. For instance, in the course of my research, questions of this type that I encountered included phone numbers for palm readers, directions to the nearest ski slope, and requests for advice and services of a sexual nature. If I was a hooker, a tour guide, or the lady who answers at Information if you succeed in not getting a machine, these would not have been stupid questions, but as I was working in a used book store, they were.
Askers of this type of stupid question are roughly evenly divided between the arrogant and ignorant (often tourists or people who are too good to touch their own phone book) and the emotionally needy and ignorant (usually abused-looking women or the mentally challenged, they generally give the impression of asking the question as much to hear a human voice as to get the answer. No, this is not flattering.)
This question is distinguished by an even greater dependence on context than the above type. Properly speaking, the question itself is not stupid, but the fact it was asked of you when the questioner could easily have found the answer for his or her self betrays an intellectual laziness and lack of observational skills that mark the questioner as stupid.
Particularly fine specimens in my collection include:
This group of questions have answers which the questionee cannot possibly know the answer to. The questioner will inevitably take an answer of "I don't know" as evidence of laziness or malice on the questionee's part.
Specimens:
This is the camouflaged snow weasel of the Stupid Question world. It sneaks up on you in the form of a perfectly valid question, and only after it has attacked - sometimes after a quite long and troubling circular conversation - do you determine that the answer to the question was not, in fact, the information that the questioner wanted to elicit. A common form is to subtlely mangle the vital stats of a book (or other product) being requested, leading to requests for "That book by Harry Potter" or "The Lord of Ocean City." More advanced questioners may consider asking for a book by its subtitle, misstating whether it is fiction or non-, and, when shelves are being examined, describing it as "a green book" when the cover features a square inch of green on an otherwise yellow field. And these are just beginner's tropes. The full range of possibilities is virtually endless and totally unpredictable. Alas.
Speaking of totally unpredictable, these guys are it.
