Dueling Presleys

S4, E3: Lillian thinks that an Elvis impersonator would attract patrons to the diner. But when the King arrives, the Powell family discovers there is nothing simple about hosting a deceased superstar's double, especially since for security reasons, he will not stay in a hotel. Since Elvis only sleeps during the day, Charles, who has been nominated to share a bedroom with the entertainer, is kept awake all night by his rehearsing. Elvis confides in Charles that his name is really Wendell, and the reason he became Elvis was to avoid getting hurt after the love of his life walked out on him.
