Caught with a smoking pun

Is there any news subject more likely to have a pun in its story title than a smoking-related issue? I would be surprised. I think sub-editors the world over rub their hands with delight when a new smoking story puffs in the door. From my large collection of articles on smoking, close to half of them have puns in the title. From "Where there's smoke, there's ire" to "Smoke promotion stubbed out" to "Tobacco controls vanish in a puff of smoke" to double-headers like "Pubs read the smoke signals and choose to butt out early". It's a phenomenon that shows no signs of running out of puff.
