It appears my joke non-answer was accepted by the questioner for some reason. Obviously, this does a disservice to anyone who might run across the question later on. Obviously, I voted up the other, better answers, but my answer will still be nailed to the top of the answer stack.
My guess is that the responsible thing is to delete my dumb answer. Maybe turn it into a comment. But not everyone will be willing to do that, especially if they have received a lot of upvotes on the post. Actually, I suppose it helped my reputation to have it accepted, so the system provides an incentive to stay quiet.
What do you think I should do?
