There were a few short catfights at the end of various episodes of the TV show Hart to Hart (e.g. in the episodes "Max's Waltz", "Ex-Wives Can Be Murder", "A Lighter Hart", "A Couple of Harts" and "Hartland Express"), usually when Jonathan Hart fought with a villain, and the villainess went to retrieve his dropped gun, only to be pounced on and disarmed by Jennifer Hart. And there were a few episodes (like "Rich and Hartless") where the villainess was about to get to the gun, but where Jennifer stopped her in other ways. One such episode is "Death in the Slow Lane", where the arrogant, over-confident villainess gets the gun, but where Jennifer sprays her in the face with liquid from a power jet, causing her to drop the gun.
Here's an alternative ending that I wrote for someone who liked the Hart to Hart catfights, describing what might have happened if there'd been a catfight in skirts and heels:
As Jonathan Hart powered into the man holding him and Jennifer at gunpoint, the blonde spy gasps in panic. If she and her husband can take possession of the car and permanently dispose of these two interfering witnesses, they'll get clean away, and complete their espionage mission, leading to promotions and other rewards from their paymasters. But if they're caught, it's going to be life in prison, given that they shot the car dealer who sold the Harts the vehicle.
The blonde spy eyes her husband's gun on the stone floor of the garage, dropped after Mr Hart slammed into him - the two men now trading punches and struggling some distance away, up against the wall on the other side of the garage. The icy blonde glances briefly at Mrs Hart, then steps quickly towards the fallen gun and scoops it up. But Jennifer Hart reacts quickly, knowing her life is at stake, as this murdering blonde clearly plans to kill her, then kill Jonathan.
