Synopsis by Hal Erickson
Joyce Jameson guest stars as the title character, a mercenary moll named JoJo Tyler. Dispatched to Long Island to retrieve UNCLE's ion-projecting machine, Solo and Illya receive the unexpected assistance of JoJo, the girlfriend of THRUSH agent Harry Pendleton (Fabrizio Mioni). The two men from UNCLE must bank upon JoJo's self-serving relationship with Pendleton's superior Simon Baldinado (Robert Strauss), whose fondness for the girl causes him to become careless -- perhaps fatally so. Written by Peter Allan Fields, "The Dippy Blonde Affair" was first broadcast on January 7, 1966.
