How did I never know that 666 in Roman numerals was just descending letter values starting with D? That's very cool, and makes me wonder if that is part of its origin.

Ashamed to say I had to look that up. I can usually figure Roman numerals pretty quick. :( I'm losing it as I age. Person. Woman. Man. Camera. TV.

I'm supposed to believe they were somehow wearing gloves and dyeing clothes with those nails?

Ouch. It hurts to look at with that thought.

I had the same thought and I was like damn this person is going to lose those fingers

I mean… seems like you just need to poke a hole in each finger of a tight rubber glove and then dip your hand in dye. You might try something like henna or India ink rather than clothing dye though.

Most of the dye will be in the dead layer of skin and will naturally come off in a few days. Scrubbing will accelerate it but can also make the skin raw.

That might enhance the effect.
