They say that the United State Senate is the most exclusive club in America. If you are considering things in terms of how only rich people who are overwhelming white and male have been allowed in, that is probably true. If you want to consider a more egalitarian and democratic club as the most exclusive in America, look no further than the tiny little club inhabited by comedy movies that have taken home the Oscar for Best Picture. Keep in mind that the exclusivity of this club is directly related to the expansion of the definition of what makes a comedy that has taken place over the decades.
