Are you sitting there this Labor Day weekend wishing you could be the next Mark Twain? The reincarnation of Kurt Vonnegut? Well, you need to know about satire:
the use of humor, irony, exaggeration, or ridicule to expose and criticize people's stupidity or vices, particularly in the contextof contemporary politics and other topical issues.
It's been said that humor is a corrective social device – it presents imaginary or exaggerated situations that poke at falsity, whether in an individual's ego, or in the more collective social sense, but it does so without being seen as a diatribe or personal attack. In this way, for instance, a supremely vain person will see him/herself in a joke or witticism, will then consider his/her own behavior, and hopefully moderate it.
Politics is a fertile field for correction through satire, and Jon Stewart is possibly the best at it today. Forget for a few moments which side of today's ideological divide you fall on, and pay attention to how Stewart deals with satire in this interview.
