The Idiots (1998)

A group of perfectly intelligent young people decide to react to society's cult of aimless, non-creative and non-responsible form intellect by living together in a community of "idiots". Their main activity becomes going out into the world of "normal" people and pretending to be mentally retarded. They take advantage of this situation to create anarchy everywhere they go and try by every possible means to make people annoyed, disturbed, miserable, ridiculous, angered, and shocked. The film starts as they recruit a new lost soul and introduce her to their megalomaniac leader.
