 Bob's three most frequently seen regular patients are the cynical, mean-spirited and neurotic Elliot Carlin (Jack Riley), the milquetoast Marine veteran cook, Emile Peterson (John Fiedler), and quiet, reserved Lillian Bakerman (Florida Friebus), an older woman who spends most of her sessions knitting.Carlin was ranked 49th in "TV Guide"'s List of the 50 Greatest TV Characters of All Time, and Riley reprised the character in guest appearances on both "St.Elsewhere" and "Newhart".
