Double Standard: Yugi chastises Marik for taking control of other people to use for dueling, but has no problem with letting Yami take control of his body to do the exact same thing.
Marik: Oh right, because when I take control of somebody to make them play a card game, that's "pure evil." But when you do it, it's like you're Mother friggin' Teresa!
Everyone Hates Mimes: Yugi loses all reservations about hurting the person that Marik has brainwashed into attacking him once he finds out that said person is a mime.
Geeky Turn-On: This will be the first of many moments in the series where Kaiba gets a boner at the mention of an Egyptian god card.
