You must be kin to my late father-in-law (see the .44 special thread section about his inclination for possum, and this might make sense).
He had my mother-in-law percolate his coffee the night before so it could "set-up" a little before he drank it the next morning.
It resembled burnt motor oil....about 40 weight.
I think I'd just rather drink Sterno.

My Dad worked out of the house, free-lance industrial designer. He had this big aluminum coffee percolator, 10-12 cups maybe? Here was his routine every morning:
1. Get up
2. Get dressed
3. Plug coffee pot in with left-over coffee from day before
4. Make toast
5. Tap off last cup, clean pot, set up and start brewing new batch
6. Take toast, day-old warmed up coffee to the dining room, have breakfast (coffee and toast), then a cigarette while new pot percolated
7. Drink all but 1 cup during the rest of the day
8. Next day, start over at #1
