So, if for some reason you don't want to watch that video (it's fine), their number-crunching determined that 262 fun-size candy bars in one sitting would be plenty to kill off an otherwise healthy, 180lb human person. That's about $30 worth of candy, 20,000 calories, or 5.5lbs of sugar.
According to the video, that would also amount to 1,627 pieces of candy corn, if you are a monster and would eat more than one piece of candy corn per decade. Basically, your liver wouldn't be able to process the amount of sugar consumed -- which is fair, as your liver probably works pretty hard as is.
Do what you will with that information. Maybe limit the kiddies to one lil' Snickers bar per visit. Perhaps serve up apples, which can aptly be described as nature's candy. But whatever you do, don't become the "pencil lady" of your 'hood.
