Ba-da-da-da who would love eating 20 McDonald's cheeseburgers in one sitting? Anyone? Bueller? Don't get me wrong, I am down with a CB - just not twenty of them! It took competitive eater Nela Zisser 16 minutes and 11 seconds to do the deed. According to Nela the colder the burgers got, the harder it was to eat. See Nela in action in the video below. You may have the urge to make a McDonald's run afterward, or not so much.
