This one is too good to pass up:
The cubic content of the skull obtained by determining the cubage of small shot, seeds, or beads required to fill the skull.
How does one go about determining the amount of small shot, seeds, or beads required to fill the skull? Does the one to be measured (measuree) tilt their head to the side and the measurer begins stuffing small shot, seeds, or beads into their skull via the ear and nose?
Can I be the measurer rather than the measuree?
