Are there any stupid questions?

This has been asked but not in a while. Prompted by the common saying but also by two recent questions self-identified as “stupid.” (Also, asked because it’s dead in the water here today and we need something to liven things up.) As a librarian who’s been asked plenty of questions, I’ll hold my fire. Can be taken re: Fluther or life in general as I put it in Social rather than Meta.
