Anyone who’s ever found themselves stuck wondering exactly what a bag of dicks would look like knows Boston stand-up Louis C.K. has a sick, sick mind. Far from your garden-variety family — to use a term loosely — comedian, C.K. riddles his bon mots with quizzical sexual imagery, bizarre observations on human anatomy, admissions of vice and insults at the expense of his own children. Like many comics, C.K. cut his teeth behind the curtain, writing jokes for the likes of David Letterman, Conan O’Brien, Dana Carvey and Chris Rock before a run of stellar HBO stand-up specials landed him his own show on the network — the R-rated sitcom, Lucky Louie. While that show was a humorous and oft-crass take-down of domestic oblivion — think Married With Children with a heaping helping of vulgarity in place of every innuendo — was regrettably short-lived, it established C.K. as a force to be reckoned with on the comedy landscape, garnering him his new quasi-autobiographical series on FX, Louie, which premiered last month. Still, to the backbone of the comedy audience — dorm-room stoners and unkempt ne’er-do-wells — his most celebrated work will perhaps always be the lovably hysterical Blaxploitation spoof Pootie Tang — a directorial vehicle which can only be seen as his Citizen Kane.
