I'm looking for questions that I can put to interviewees that will piss them off or make them feel stupid. The aim is that if i decide half way through a technical interview that they're not going to get the job, i need some of these to continue with.

So far, I've got ...

i) What language is PL/SQL syntax based on (answer ADA, as discussed in the forums a while ago. This I would classify as a stupid interview question.)

ii) How do you populate a number column with a value of positive or negative infinity? (answer, you have to import it from an Oracle 5 database. This would be an obscure question)

Well you see the pattern. There's a real answer, but who gives a crap about it?

Anyone else got any?
