I love the film by Monty Python, 'Life of Brian'. In one scene Brian awakes to find a hoard of religious followers, who have incorrectly concluded he is the Messiah, have camped outside his house.
Desparate to convince them they shouldnt follow him, he tries to rationalize that they are all different; the genius is that every one of the thousands of followers all recount his words back to him in unison 'Yes, we are all different!', except for one little man who piles irony on top of irony by saying 'I'm not', and thereby showing his differentiation.
Uniqueness is rare indeed.
