In hindsight, it's no surprise that "planking" made the cover of Life magazine back in the fifties. A). It's pleasant. B). It is a rip-roaring, damn good time. And C). it refrains from showing cleavage, suggestive hip movement nor does it further promote any sexual promiscuity by hiding any indication that the "planker" is sexually aroused.
In 1950's foresight however, who would have thought that Chesterfield Cigarettes would have fallen off the map by the turn of the millennium? These cigarettes A). not only contained the world's premium tobaccos, but B). also maintained a freshness standard that would make any 1950's nicotine-slave moist in their unmentionables. And for the record, Chesterfields were C). wrapped in cigarette paper of the highest quality- paper most likely made from organically grown redwood trees, raised in a smoke and pollution-free environment, and tended to for centuries by blonde virgins who refused membership in the now defunct Virgin Blonde Workers Union of America.
"Playing it Safe" and "Planking it Safe" may have applied to cigarettes and planking back then, but those days are over. Why plank on the floor when these days you can plank on a golf cart and become an immortalized YouTube video sensation? Why smoke an actual cigarette when you can smoke an electric cigarette of which the effects on your health are still yet to be known? Why plank on some random plankable object then get up and smoke a cigarette standing up, when you can chief cigarettes whilst planking on an inflatable kiddy pool filled with gasoline all the while being covered in baby oil on a bright sunny day? (Sorry, no YouTubey yet.)
Chesterfield Cigarettes are really just tobacco sticks laced with irony, which makes this particular ad kosher. It is more glaringly ironic to note that once you are dead and nine feet underground, you are essentially in prime planking formation for all of eternity.
..until some necrophiliac digs you up and planks you in your dead corpse that is.
