Like imagine a game where you have metal boots and the final boss is literally Adolf Hitler and you just keep running up to him and kicking him in the balls until finally there is a loud cracking noise with an animation of the glass of the screen breaking, over which you hear him screaming, "NEIN! MIEN TESTICLES!!" as he falls to his knees grasping his crotch with both hands. The final cutscene is him whimpering on the floor, grasping at his limp sack, now filled with nothing but paste.
You hear the voice of Benjamin Franklin congratulating you, "Good job! You've destroyed Hitler's testicles! He won't be commanding any more armies without those! YOU WIN!"
