LOS ANGELES, July 31 (UPI) -- Tim Conway, Paul Dooley, Ron Glass, Marion Ross and Doris Roberts will guest star on an upcoming episode of the U.S. police drama "Major Crimes," TNT said. Called "There's No Place Like Home," their episode is to air Monday. I read the script and immediately said, 'I don't want to do it.' No," Conway laughed in a promotional video posted by TNT online Wednesday. "Just to be with everybody on the set is TV history," noted Roberts. "We came here to have fun and we're having a ball," Ross added. Now in its second season, the show is a spinoff of "The Closer" and stars Mary McDonnell as a Los Angeles Police Department captain in charged of the major crimes division.
