The Narrator of "How Not to be Seen" appears in Monty Python's Flying Circus. He narrates the Monty Python sketch "How Not to be Seen". It is disguised as a public service announcement about not being seen, but is in actuality just an excuse for the narrator to kill people. All of the people are hiding from the narrator, but he knows where they are hiding. He shoots them when they reveal themselves and blows up their hiding spots. He then starts blowing up several buildings, then cities, countys, and whole countires, all while laughing manically. He is one of the few examples of a homicidal terrorist played for laughs.
The skecth was remade in And Now For Something Completely Different as the opening sketch of the film, in which the narrator is John Cleese's BBC announcer character.
