Another question: What do one of Isaac Asimov's Robot stories, a certain Jim Carey movie, and this puzzle have in common?

I was thinking of "Liar!", "Liar! Liar!", and this puzzle. This is not a castigation of the puzzle by the way! Just like with the Thermodynamics violating puzzles, the whole point of the puzzle is figuring out where the lie is!

the lie is: "Since the two diameters meet at point P, the two spheres intersect the plane and create two intersecting circles, as shown"
Leaving aside extreme cases, the circles wouldn't intersect. They'd have the same center, through which you can draw the one and only perpendicular line you're looking for.
