I wonder why this question about King Joffrey was closed.
Of course the question in the title has an obvious answer, which can be answered by merely making the effort of watching the first few chapters of the TV show. I'm annoyed by the lack of effort in this question, but my annoyance is not reason enough to close it. I'd downvote it instead -- which I actually did.
So was it closed because the title and the actual question do not match? (The title seems to ask about who Joffrey's parents are, but the question ponders whether his true parentage is the source of his alleged madness).
I think one of the two questions is constructive, if a bit obvious. Can the question be salvaged by actually asking what's in the title, or going the other way and asking about Joffrey's madness? Is it worth editing it, or should we wait for the original asker to do it?
