Storyful's senior video producer Sam Matthews joins Cheddar to reveal the videos that went viral this week. The first video on deck features an anonymous postal worker who continued delivering mail to a California neighborhood wiped out by the wildfires. The next video takes a look at a gym enthusiast who prepares for a competition. Maggi Thorne shows off just how fit she is by running on not one treadmill but seven! Lastly, we end with a confused yet adorable dog. Owner Jessica throws a ball up in the air and her rather perplexed dog, Blue, looks up to the moon and waits for her ball to return. The owner told Storyful that this isn't the first time the pooch has mistaken the moon for her ball.
