The funniest comedian on the planet is doing an experiment. Instead of taking a check from HBO, Showtime, or some other censor-free media outlet, Louis C.K. decided he'd release his new hour-long show — full of all-new material, and edited and directed by the man himself — in DRM-free HD format, directly from his website. The result is Louis CK: Live at the Beacon Theater ($5), or the funniest thing you'll watch for $5 this year. We could go on, but really? It's $5. Just buy it.
