Title: I Like To Watch
The term I Like To Watch is sometimes used to refer to sexual voyeurism, but also refers to the classic 1979 film Being There, a tale of a simpleton with no real-world experience -- all his life he's been in a single house with an old TV set (hence "I Like To Watch") and who has literally no experience with the outside world. When his guardian dies, he is forced to venture forth and through fortuitous circumstance, through those around him reading far more depth into his simple-minded observations and comments than there are, becomes a widely followed observer of life and politics. The simpleton, named Chance, sees the real world as a big TV show.
Visual: Opening sequence
The episode's opening sequence is similar to that of the movie Snatch.
