You're absolutely wracked with guilt at 'Hangmen' - from laughing so hard at the many, many inappropriate jokes. A crude sight gag near the end had me practically dry heaving. That nonstop naughtiness is what makes Martin McDonagh's killer satire the best new play on Broadway by a green mile. The Brit's comedy, which opened Thursday night at the Golden Theatre, is a heaping scoop of jaw-droppers and taboos - albeit with a sophisticated takeaway about the justice system - that'll make wimps clutch their pearls for dear life. The rest of us can't help but chuckle at the macabre madness.
