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.
Princess Mira: (aafter hearing I and Am's plan to capture Jack) You're on the right track, but the two of you could never defeat Jack. Jack is cunning and hard to restrain. By leaving him a sword he stays in the game.
Princess Mira: Have you always been this stupid?
Boris: Yes!! (pause) What? Uh, huh?
This is the first time that Phil LaMarr is not credited in an episode, either as Jack or as a secondary voice/character.
Gentlemen: Knife in Leaf
The Gentlemen manages to stick a leaf to the wall by throwing a knife at it, much like in Akira Kurosawa's "Yojimbo" when Sanjuro sticks a leaf to the floor by doing the same.
I and Am: Appearance
The Siamese killer twins, I and Am, are an acknowledgement of the Disney Siamese cats Si and Am from the movie Lady and the Tramp. In the movie they sing the song "I am Siamese If You Please."
Princess Mira: Appearance
It might be a long shot, but given her looks, Mira might be meant as an evil version of Samus, the heroine of Nintendo's "Metroid."
