How do they get those massive construction cranes down from the tops of the really tall skyscrapers when they're done building?

Sometimes they just leave them up there, to annoy people like you.

They are somewhat correct. Actually there are a few different systems used in multilevel construction. To get them there to begin with is done by two or more small cranes that are retrofitted to the levels already built lifting one another(in parts) to higher levels. And so it is the same coming down until a ground crane tall enough can take the load.

In very tall buildings the tower crane's vertical frame usually sits in an elevator shaft. Initially it sits on its own base but as the building gets higher the crane is lifted using hydraulic jacks locked into the floor or floors above as they are completed. The construction of these cranes is rather ingenious in that they can dismantle themselves and the respective components lowered to the ground.

the massive ones usually require another even more massive mobile crane to show up on site

They disassemble them and take them down piece by piece.
