Once, long ago, an angel and a demon (let’s call them, say, Aziraphale and Crowley) set about creating the most exemplary demonstration of their respective powers.
Lo and behold, a new entity was born, the perfect encapsulation of all of heaven and hell combined. And they named it Comic-Con.
For the blessed few, there was dancing in the streets, and joys innumerable and everlasting.
For the rest of us, there was much pain, wailing, and gnashing of teeth.
And Aziraphale and Crowley looked over all that they had created, and they were very pleased.
