There is a very funny scene in the 1994 holiday-season film The Ref which stars Dennis Leary, Judy Davis, and Kevin Spacey.
In the scene, the character Gus (Leary), a cat-burglar who is on the run from local authorities, exquisitely demonstrates the need to sometimes simply call a spade a spade.
Gus is holding Lloyd and Caroline Chasseur (Spacey & Davis) hostage in their own home. He becomes frustrated with the constant bickering between the married couple. An argument ensues about whether the husband did or did not see a stop sign that he had driven through in an earlier scene, and Gus finally snaps.
What follows goes something like this:
Gus: You saw the stop sign, didn't you Lloyd?
Lloyd: (Stares nervously at the weapon pointed in his face)
Gus: You saw the stop sign, didn't you Lloyd?
Lloyd: (Whispers) Yes.
Gus: Then you, are a liar. Capital “L”, small “i”, small “a”, small “r”, period.
