Flying Circus popularised innovative formal techniques, such as the cold open, in which an episode began without the traditional opening titles or announcements. An example of this is the "It's" man: Palin in Robinson Crusoe garb, making a tortuous journey across various terrains, before finally approaching the camera to state, "It's...", only to be then cut off by the title sequence and theme song. On several occasions the cold open lasted until mid show, after which the regular opening titles ran. Occasionally the Pythons tricked viewers by rolling the closing credits halfway through the show, usually continuing the joke by fading to the familiar globe logo used for BBC continuity, over which Cleese would parody the clipped tones of a BBC announcer. On one occasion the credits ran directly after the opening titles. They also experimented with ending segments by cutting abruptly to another scene or animation, walking offstage, addressing the camera (breaking the fourth wall), or introducing a totally unrelated event or character. A classic example of this approach was the use of Chapman's "Colonel" character, who walked into several sketches and ordered them to be stopped because things were becoming "far too silly". Another favourite way of ending sketches was to drop a cartoonish "16-ton weight" prop on one of the characters when the sketch seemed to be losing momentum, or a knight in full armour (played by Terry Gilliam) would wander on-set and hit characters over the head with a rubber chicken,[12] before cutting to the next scene. Another innovative way of changing scenes was when John Cleese would come in as a radio commentator and say "And now for something completely different".
