there was this day, all long time ago, a man was walking down a country road, as sad as a person could be!
and as this man was waking down this road, he came upon , this here donkey, with his mouth stuck wide open, (the donkey) and the man asked the donkey how this happen,
and the donkey told the man, that he heard a joke, from the barnyard, and he laughed so hard that his jaw got stuck!
so beware don't go telling a joke, where a donkey can hear! :)
