In what can only be summed up with, "Wow, that's slightly disturbing," an experiment to see what would happen if a McDonald's Happy Meal was left out for a year seems to have gone terribly...right? Sure, the meat shriveled and the bun went completely stale, but the meal seemed to still hold the properties prime for a photo shoot. Eating it now would not be in anyone's best interest, but that should go without saying.
