In the episode where Robbie meets Marie, and Mary has dinner with Wilson, Mary calls Lucy to ask her if she should have dinner with Wilson. Their mom (Annie) comes in and Lucy tells her Mary is on the phone. She tells Mary to hold on, and holds the phone against her chest. Then, the camera goes off Lucy, and Annie picks up the phone right off the hook, when Lucy was just holding it on her chest. The phone had somehow magically gotten on the hook again when Annie picked it up.
