Idiocracy
I'm watching Idiocracy right now and its funny and scary. Basically, imagine what would happen if the world regressed due to stupid people procreating more than smart people. 500 years later, everything stupid in society has become mainstream. I don't even remember this movie coming out, which is no surprise since the studio virtually buried its release, some say due to brand trashing. Costco, Starbucks, Fuddruckers and Carl's Jr. are all reduced to base urges. Not exactly a laugh riot, but worth a look.
