TipEx (a Commonwealth analogue for Wite-Out and other correction-tape products) has an ingenious and engaging YouTube marketing campaign: a video called “NSFW: A hunter shoots a bear,” branches off into a kind of video-text-adventure, where you are invited to type verbs into a box and see what the bear and the hunter do with one another (you can get funny results out of “f*ck,” of course, and also “gets high with” and “dances” — I’m sure there’s more). It’s a kind of next-generation Subservient Chicken, and the (no doubt blisteringly expensive) creative reworking of YouTube’s familiar user-interface makes it even more click-trancey than its forebears.
