Harrison has found numerous methods of crawling. He started off army-crawling, which he still uses every now and then. He then figured out how to do the traditional crawl. Then it was on to the scooting on the bum across the floor. The most recent one is what we refer to as the "Left-Leg Lopez." All of the fans of the group TLC will know where we got that name from. He switches between all of his methods at any given time. Anyway, we think it is hilarious and you can see a glimpse of it here in the video.
