You can't handle the truth

Expression first popularised by Jack Nicholson in the character of Col. Nathan R. Jessep in A Few Good Men (1992, dir. Rob Reiner), when he blows up in court in Tom Cruise's face. Handy exclamation to direct at the computer screen when somebody votes down an eminently rational definition on urbandictionary. Parodied by Sideshow Bob in an episode of The Simpsons ("Pish! I deride your truth-handling abilities!").
