Maybe the fates got clumsy.
Maybe Poseidon had one of his angry days.
However it happened, the underworld is overcrowded, and Zeus has ordered Hades to let some spirits out.
Hades arranges all the souls of the dead in a line before Cerberus.
When one of his three heads bites down on the soul in front of it, they'll get returned to the land of the living.
Anyone to the left must get out of line and stay in Hades forever.
And everyone else shuffles forward, at which point Cerberus will feed again.
Each of the dog's heads has an equal chance of being the one to bite each time, and no two ever bite simultaneously.
Unfortunately, Hades' minions forgot to tell you what was happening, and by the time you show up there are only 99 souls left in line.
Hades looks furious and drawing attention to yourself won't end well.
