Waterhouse steals a container of a revolutionary nuclear rocket fuel from the laboratory of the late Dr. Harper, beating CONTROL agents Maxwell Smart and 99 to the punch, and delivers it to the Bulmanian embassy. Two days after performing this "valuable service" he is executed - in front of his wife - by the Ambassador by the ironic means of a celebratory glass of poisoned Bulmanian muscatel because KAOS has "decided that he knew too much". Portrayed by John Trayne [Episode #132: "How Green Was My Valet"].
