Melvin stumbles across footage of the episode with his favorite joke in it... "new episodes every week"!
"Aaaaah! Exodia! It's not possible! Nobody's ever been able to summon him... except for that one time!"
Gozaburo: ...are you okay?
Kaiba: Uh, yeah. I'm fine.
Death Equals Redemption: Defied. Noah is the only one who actually thinks that dying to protect people from a problem that you caused in the first place means anything.
Enemy Mine: Noah teams up with the heroes after being betrayed by his father.
Expy: Mokuba plays a game called "Pharaoh Fighter". Not only is the game itself a Street Fighter expy, it also includes characters like "Bacula" and "Yoogy".
Grand Theft Me: Noah steals Mokuba's body so that he'll be able to enter the real world.
Hypocritical Humor: Kaiba tries to condemn Gozaburo for relying on a single monster to pull him through a duel. Gozaburo points out that Kaiba does the same thing all the time with his Blue Eyes.
Naked on Revival: When fusing with his father to ground them both in the Virtual World, Noah is... naked for some reason.
Self-Deprecation: Apparently spoofing the aforementioned Old Shame wasn't enough; the current episodes get plenty of flak as well.
Unexplained Recovery: Tristan is suddenly and inexplicably cured from being a robot monkey.
What Measure Is a Non-Human?: Melvin gleefully notes that he can create horrific on-screen violence without censorship as long as his victims are robots instead of real people.
