The tribe shouldn't have too much trouble removing the knots and ropes from their wooden cage in order to escape.
The Fall and Winter segments have zero dialogue (unless you count cackling.)
Trivia: The Scotsman challenges Jack with the following contests: Long distance rock throwing, long distance running, high jump, target javelin, speed swordmanship, fishing (using only your mouth), sand castle building, knocking down bananas with rocks by only hitting the stem, long jump, tic-tac-toe, and finally thumb-wrestling.
Unlike his former two appearances, the Scotsman no longer has to hold the "grip" of his machine-gun peg-leg to fire it.
It was incredibly conventient that the Scotsman was riding on the boat that Jack was serving on after such a short time for there to be "sandal tracks."
Exactly where did I and Am store their weapons? They didn't seem to be wearing any bags or pouches or anything.
The member of the pair of "fraternal twins" bounty hunters who waits for Jack in the pit is the white one - except for the moment he pops out with the chain. For that moment, he's drawn as the brown one.
Trivia: Da Samurai mentions videotapes in the last scene; apparently, even in this futuristic world, DVDs have not yet totally replaced them.
After Jack has cut the two 'sticks' he sheaths his sword then he tosses one to Da Samurai. In the next shot is medium range and Jack is shown holding his sword but in the following closeup Jack has the stick in his hand.
After defeating the Ninja, Jack pulls his sword out from the wood. The sword is longer than the thickness of the wood, but did not seem to go through. Retractable perhaps? :)
When Jack emerges from the water, his hair is askew - then the gigantic monster strikes and Jack's hair is immediately tied in its typical topknot.
Jack has a small candle which he lights, he then pulls the other half over it. This then creates a flashlight effect. Wouldn't the candle burn through the material? And if it is fire-proof, wouldn't it just put out the fire? Besides, it wouldn't focus the light into a beam anyway, would it?
When the thief is going over the security laser beams, wouldn't the tails of his coat hang down and trip the alarm?
What is a janitor's closet doing in one of Aku's high-security vaults? Exactly who is the janitor?
The diamond pattern on the sword's handle is not seen for most of the episode.
When Jack's father is riding the horse, you see the moon is a cresent with a star within its shape. The star which the cresent surrounds shouldn't be there unless the star was in front of the moon (which is impossible) or the moon is actually a cresent (in which case, it wouldn't be able to orbit the planet).
Trivia: Aku's first act of evil when he comes to Earth: annihilating the dinosaurs.
When Aku comes to Earth it is the time of the dinosaurs, but when Earth is shown the landscape is not Pangea.
When the monk that gives Jack's father the elixir is seen from a faraway view, the container of the poison is like a cup. When the view zooms in, it looks like a perfume bottle. Then when Jack's father puts it in his belt, it's a cup again.
Odin wields a trident, but in Norse mythology, Odin wielded a spear called Gungnir, which never misses its target.
