A cute thing to do whenever someone sandbags you with trivia is to suggest going over to the developer desks and asking everyone in turn if they know the answer. If you find someone that does, you answered the question. If you don't, then you suggest doing a web search, and you have also shamed your interviewer. If they don't wave you off at the suggestion, you also get to meet everyone and see their work environment.
