After the Dunphy's elderly neighbor Walt passes away on "Modern Family" (Wed., 9 p.m. ET on ABC), Claire was worried that Luke would have difficulty processing it. But perhaps she should have been more concerned with how she processes death. Apparently, no one ever told her that she has a tendency to smile; especially when talking about it to others. By the end of the episode, she was at Walt's house and had to break the news to two different people that showed up, and both of them were disgusted and disturbed by her laughter and smiling. The show juggled three other plotlines alongside the death of Walt.
