Point of interest sir, it also means bloody

Have you checked your humors today? Not the gunky jelly stuff in people’s eyes, the other kind.

Are you melancholic, phlegmatic, sanguine, or choleric? Are you a salamander, gnome, nymph or sylph? Earth, water, air or fire? Elf, Ninja, Pirate or Dwarf? (arrrr! buckets of blood! flagons of phlegm and barrels of black bile!)

If nothing else, the theory of humors adds to one’s arcane vocabulary.
