s04e07 Meatball Montecito

Jimmy "The Chin" Aversano (Guest Star Vincent Pastore), a black listed mobster, purchases the Montecito's million dollar wedding package for his daughter, which includes a fully catered wedding, luxury treatment, a Harry Winston engagement ring and Wayne Newton (Guest Staring as himself). However, problems arise because Ed (James Caan) and Wayne Newton are on bad terms, someone stole the diamonds, and with many of the wedding guests allegedly members of the mafia, the suspect list is a mile long. Meanwhile, Sam (Vanessa Marcil) hosts Sharkey Rosenthal (Bill Macy), a whale nearing the end of his life. Elsewhere, Danny (Josh Duhamel) and Delinda (Molly Sims) are finding out that living together is not as easy as it seems.
