They say that with age comes wisdom. Well, I don’t know about that, but if this video is any indication of the truth, with age comes a willingness to have fun. The grandpa you see in the images decided he wanted to give his grandchildren a memory that they will never forget. He managed to do just that, but in a way that will most likely surprise you. With his son recording and his grandchildren by his side, grandpa emptied the swimming pool in the most fun way possible. The kids never saw it coming. Hilarious!
