1. A dog is heading home after finding a big, juicy bone. On his way home, he happens upon a river and sees his reflection in the water. He thinks he sees another dog with a bigger, better bone than the one he has. Therefore, he barks at the "other" dog to try to get his bone. When he barks, his bone falls out of his mouth and he has to go home with no bone at all.
