How I usually try to answer these kinds of questions is "Shooting yourself is generally not a good idea, for these reasons. If you really want to do it, you can try loading your gun and pulling the trigger again, but a better alternative might be to take off your shoe by untying your shoelaces and carefully pulling on your shoe, following the curve of your foot."

But it's hard! On the one hand, you don't want to teach people to do the wrong thing (especially not on SO, where answers are often copied wholesale and pasted into production code), but also not answering the question as asked usually doesn't help the OP at all.

If it's not clear what they're trying to achieve I usually leave a comment asking for clarification rather than answering, though.
