A ghost once used its entire deathtime's savings to purchase a mainframe computer, to make possible the calculation of some of the parameters of the afterlife, I don't know which ones. But after operating for many hours at a frantic pace, the device froze.
“Bother!” exclaimed the ghost. “It must be jammed on the inside. I had better find out what the trouble is.”
The ghost was the romantic partner of a skeleton and didn't want to be the victim of sarcasm when it became obvious what a waste of money the machine had been. “I ought to try and fix it before 'Bones' gets back,” the ghost said to itself in desperation.
So it floated through the computer and ended up on the inside, but one of its wisps got snagged on a diode and it couldn't get back out. When the skeleton returned from work and heard the cries for help emanating from within the mainframe, it was astonished and thought there was some deep symbolic meaning in this incident.
“I didn't know computers had souls!” it gasped.
¶ They don't yet; but one day they might.
