The Osbournes' pets begin to drive Ozzy crazy, as they monopolize the house and go to the bathroom all over the floors and carpets. He believes that the situation could be brought under control if someone would simply remember to let the dogs outside to do their business, but they seem to be completely untrained. The worst offender is Jack's dog Lola, who tears up a couch cushion and leaves the most unpleasant deposits of any of the animals. Sharon finally brings in a pet therapist to deal with the situation, much to Ozzy's dismay. The woman, Tamar, offers some advice and tries to work with the animals, but it really doesn't make any difference. Lola goes to the bathroom on the floor seconds after Tamar has praised her.

Ozzy and Sharon are more than a little put off by the fact that Jack just lets Dill come over without telling them, let alone asking for permission. Dill is obnoxious and slovenly, and creeps out Ozzy and others with his habit of always scratching his head. Dill also smokes and drinks a lot, and Sharon is annoyed to find a bottle of Jack Daniels with his belongings. She decides that she is going to go to the bathroom in the bottle, but Kelly pleads with her not to do this. Dill accidentally starts a fire in the kitchen, doing damage to a pan and the stovetop.
