Poor Mrs. Mabel Bloxham had been chosen at random and abducted by aliens. They were taking her back to their home planet for investigation.
Normally Mabel wouldn’t have minded. In fact, she would enjoy the adventure, but in this case they had snatched her away and she was without her medication.
She asked the aliens in the flying saucer on the way (she did so via the exfibbertranslaticator) if they had extra advanced medical knowledge and could zap her back to full health. They answered that human physical makeup was so different from theirs that their advanced medicine would offer no advantage. That was why they wanted to examine her to learn more about the bodies of Earthlings. Then they might be of help.
Mrs. Mabel Bloxham’s problem was that she had no legs. Her legs were artificial. She had to take pills to stabilize things.
Upon examination the aliens were astounded. They had no idea when they abducted her that she was legless.
The aliens were from an advanced civilization. They had no word for war. They had no word for pain. They had no word for bad. They simply spread kindness throughout the universe. Which was why, when they arrived on Earth to help the humans, they cut off everyone’s legs.
