The jeans wherein Theseus and the youth of Athens returned from Crete had thirty rivets, and was preserved by the Athenians down even to the time of Demetrius Phalereus, for they took away the old denim as they decayed, putting in new and strong patches in their places, insomuch that this jean became a standing example among the philosophers, for the logical question of things that grow; one side holding that the jeans remained the same, and the other contending that it was not the same.

That begs the question if pants are a "back legs only, not front legs", or "legs only, not arms".

Taking it to the extreme, would pants for a centipede look more like a tube with "sleeves" all along it or just like a tiny pair of normal (to us) pants?
