We're all familiar with the Zeno's Paradox version of the race between Achilles and the Tortoise, but somewhere I read of a different race between them. In this race, Achilles passes the Tortoise soon after the start, but then passes him again and again along the race course, finally sighting the Tortoise ahead of him, just across the finish line.
The explanation is that Mr. T stationed family members along the course, and it was these--not Mr. T himself--that A kept seeing. But not having the best vision, A was taken in.
Where was this story told? I don't think it's Hofstadter (seems too simple) or Carrol.
