Sorry for the pedantry, but the classic question is “Have you stopped beating your wife?” or “When did you stop beating your wife?”. The point is that it’s a question that cannot be answered in a single word (therefore, no matter how you answer, a soundbite of your answer can be presented as damning you, or at least making you look stupid.)
“How often do you beat your wife?” can be answered with a single word: “Never.” Makes it much less effective as a dirty trick.
