Break a leg -- Chew the fat -- Come to a head -- Down to the wire -- Easy as pie -- Fly-by-night -- Get into the swing of things -- Graveyard shift -- Heart of gold -- Hit the hay -- In a nutshell -- Keep a straight face -- Knock on wood -- Like a bump on a log -- On pins and needles -- Out of the frying pan and into the fire -- Pass the buck -- Play it by ear -- Pull your leg -- The real McCoy -- Sick as a dog -- Spitting image -- Sweet tooth -- Throw in the towel -- Two cents' worth -- When in Rome -- You can lead a horse to water.
