"Could Have Avoided This!" Plot: When Pegasus reveals he arranged the whole Duelist Kingdom Tournament just to steal Yugi's Millennium Puzzle, Yami goes on a rant about how Pegasus could've just simply asked him for it.
Yami: People have died because you wanted a necklace!
Freudian Excuse: Yami Bakura provides a very flimsy one for himself. Apparently, if your parents don't love you enough and then try to name you Florence, you'll turn evil and hijack people's bodies.
The Guards Must Be Crazy: One of Pegasus's guards is able to convince himself that the loud clanking sounds Tristan's suit of armor makes is "definitely the sound that wind makes".
Kid with the Leash: Yugi starts to demonstrate some of this power over Yami for the first time.
Metaphorgotten: Grandpa launches into one during an attempt to compare playing card games to making love.
"You usually do it on a table. And you always feel deep shame when it's finished. Also, the older you get, the less fun it is. So remember: always wear a condom when playing card games."
Never Say "Die": Spoofed. Yugi's life force gets drained away from being inside the Shadow Realm, essentially dying. Yami tries waking Yugi up under the logic that he couldn't actually be dead because "4kids would've censored it."
Out of Sight, Out of Mind: Tristan sums up the trope and provides the page quote when he tosses the Millennium Ring into the forest.
And now to defeat the evil villain once and for all, by throwing him carelessly in a random direction. Go, Millennium Frisbee!
