A "Survivor" spoof kicks off this installment, which finds Syd challenging a ruthless medical rival and Robbie seeking immunity as an alliance-crazed Andi plots to frame him for arson.

John helps Syd cope with fears of losing her surgical skills for good, while Joanie supports Burt as he goes under the knife to cure his impotence; Robbie finds living quarters for Andi, who's facing arson charges for torching the game-show set; and Jim tames a pesky parrot.
