New Zealand model and unlikely competitive eater Nela Zisser demonstrates how fast she can demolish a KFC Double Down. The sandwich consists of bacon and two different kinds of melted cheese pinched in between two chicken fillets. Nela’s incredible speed-eating antics have been getting a lot of attention lately. Her practice attempts such as this one seem to be paying off, as she gets better and better! Credit: YouTube/Nela Zisser
