The announcement seemed just plausible enough: a limited edition Vaseline Lip Therapy with the savoury hint of Marmite. Promotional materials, complete with quotes from brand managers, were released, and the product was said to be available exclusively via Facebook. The internet went into a frenzy.

Of course, it was all an elaborate April Fool's Day joke. There was no such product. The campaign was so well-executed, however, that it left many wondering "what if?". It perfectly played on the brand's quirky reputation and the public's love-hate relationship with the spread. A truly memorable piece of marketing mischief.
