There are plenty of people who are confident they can come up with an workable idea for a reasonably good prompt for any canon, coalie. I can come up with fifteen ideas on command after any movie or book; the problem is making it stop. I need exchanges to narrow down what I'm going to write long enough do actually do it, not come up with ideas. I suspect a lot of the people who take this kind of pinch hit are in my boat.

Also, I really don't think anyone who picked one up today can be said to be doing it "in haste".
