Completely Missing the Point: Tea sees that Bakura has gone missing and rushes to tell Yugi... because there is now a vacant room for them to party in.
Do I Really Sound Like That?: Bakura is not impressed with Melvin's extremely hammy introduction of their shadow game, and decides that he himself must have sounded like "a total wanker" when he did something similar back in season one.
Fangirl: Bakura warns Melvin that his death would release a power far stronger than himself... his fangirls.
Gratuitous Japanese: Marik uses "aibou" (which is Japanese for "partner" and also heavily associated with Yami/Yugi slash in Fanon) while imitating Yami Yugi.
Bakura: What the bloody hell does 'aibou' mean?!
Marik: I think it's Japanese for gay.
Late to the Punchline: Marik finally understands and explains a joke Melvin made about Bakura wanting Marik inside of him... which happened in the previous episode.
Sudden Musical Ending: In the face of defeat and possible death at the hands of Melvin, Marik and Bakura decide that there's only one thing left to do: sing a rendition of "Stand By Me".
Talking to Himself: Finally gets referenced in this episode. In a credits sequence showing all of the characters and their respective voice actors, LittleKuriboh is credited with voicing forty four different characters.
Wrong Genre Savvy: Marik assumes that Yugi will show up at the last second and save them, but Yugi is too busy partying.
