"Would you believe...", "Missed it by that much!", "Sorry about that, Chief", "The Old (such-and-such) Trick", "And ... loving it", and "I asked you not to tell me that".
The series centers on bumbling secret agent Maxwell Smart, also known as Agent 86. His female partner is Agent 99, whose real name is never revealed in the series. Agents 86 and 99 work for "CONTROL", a secret U.S. government counter-intelligence agency based in Washington, D.C. The pair investigates and thwarts various threats to the world, though Smart's bumbling nature and demands to do things by-the-book invariably cause complications. However, Smart never fails to save the day. Looking on is the long-suffering head of CONTROL, who is addressed simply as "Chief."
