Lucy fears that she and Ricky don't have enough in common, so she decides to pursue one of his interests: camping. Ricky and Fred don't want her (or Ethel, for that matter,) horning in on their summer retreat, so Ricky decides to take Lucy on a "trial run" in the woods and make her life miserable. But Lucy is wise to his plan, and guess whose life is made miserable in the end? (thetvdb.com)
