Nokia is bringing back the mullet hairstyle. While Nokia’s Lumia 2520 tablet isn’t short at the front or long at the back, the Finnish smartphone maker’s latest ad picks a fitting mullet analogy for a truly weird promo. Nokia’s main selling point of the Lumia 2520 is "work and play" in a single tablet, just like the mullet hairstyle with business at the front, and party at the back. The long-forgotten hairstyle might have peaked in the 1980s, but that’s not stopping Nokia from reviving it for a little bit of awkward hairdressing.
