The story goes that when the famous Greek painter Apellis made a full-body painting of Alexander the Great and showed it to the audience, a shoemaker approached him and made some comments about the rendering of the sandals of the great warrior.

A lighthearted reaction upon receiving disappointing news of some sort.

However, the entire first season would instead be tedious padding and backstory before finally ending with Dracula surfing in the last five minutes of the season finale.
