Fridge / Columbo S 07 E 03

• Fridge Brilliance: When Kay leaves the projection booth to kill McAndrews, she gets a cassette recorder out of her briefcase and plays back a recording of herself counting down the four minutes she needs to do the deed. Why not just check her wristwatch, or bring a stopwatch? Because the audio countdown allowed her to keep her eyes on her surroundings and not be distracted by checking a timepiece. This is illustrated when, in her race back to the projection booth, a security guard, whom she might have missed if distracted, unexpectedly blocks her way.
