This post contains some spoilers, but I consider it outside the statute of limitations for such things.
There’s this old movie where aliens are concerned about humanity developing a weapon that if used would Destroy the universe.
So the aliens use a really stupid plan to try and convince us to stop. And I guess this was after 8 other ideas either failed or were considered even worse.
Anyway at the end (of course) humanity wins and drives off the aliens. Wait, what was the aliens’ original goal? Something about the universe? Oh well, must not be important… The End.
