I have seen on tv and the sides of buses ads for a new food product with the slogan ‘Just eat it’ (no link – no free advertising here!). Maybe the tv ad has it too, but the ad on the sides of buses includes a Twitter hashtag #justateit. Why the past tense? Why not #justeatit. Surely anything that gets the customers tittering is a fair marketing ploy.
[PS I’m not particularly a Weird Al fan, so I didn’t think of this until later.]
