Yu-Gi-Oh!: The Abridged Series/Fridge

Fridge Brilliance

 * In Yu-Gi-Oh!: The Abridged Series, during the 4th Council of Doom, Dartz demands Mai Valentine's dick, but that makes sense only when Marik said in the 1st Council of Doom, "There are no women in Yu-Gi-Oh! There are only extremely girly men!" On a second thought, that might be Fridge Horror.
 * But Dartz wanted her (card) DECK, it was his pronunciation issues that made it sound like he said the other word so your point is moot.
 * Well, one of the henchmen did vomit when Dartz said that.
 * In BBT Abridged, Jaden obsesses over Paradox attacking Venice. Why? Because Yusei said if he could tell him why they were in Venice he'd let him ride his motorcycle. Jaden's trying to find out to take up Yusei's offer.
 * Although (possibly?) unintentional, Shadi's hatred of the Jews does make sense...
 * Also, he's a parody of the character Borat, who shares his Irrational Hatred of Jews and his distinctive catchphrases.
 * Why does Celtic Guardian seem to hate the Blue Eyes White Dragon so much? Remember when Yugi and Kaiba last dueled? Blue Eyes destroyed Celtic Guardian and defeated Yugi. He still has a grudge.
 * On the subject of Dragons, Yugi makes fun of Kaiba's fetish for dragons, one season later we learn about his hot dragon girlfriend from his past life.
 * In this video, the Cybernetic Ghost of Christmas Past From the Future claims that there is no deity. At first, this causes a bit of confusion given that there are gods in the story's universe, as confirmed by Shadi, but just think back to when Kaiba first saw the ghost. He specifically said he really needed to lay off the drugs. Therefore, the ghost is just a product of Kaiba's subconscious and is only echoing what he himself believes since, by his own admission, he is "the most skeptical person on the planet".
 * By Season 3 everyone seems to reference the real world a lot (even for the show standards). In other words they're Breaking the Fourth Wall. The same Fourth Wall that collapsed during the Season 2 Finale.
 * In Florence's Day in The Limelight, the first thing he does is break up with Zorc because he says he's started seeing another villain, one who doesn't want to destroy the world. What happened to him in the previous episode? He met Marik Ishtar, whose most evil plan to date is pushing Yugi Mutou off a boat.
 * Also in this episode, Florence seems to contradict his bieng gay and not British by telling a story about how he got his British accent. Said story is a reference to the speeches the Joker made about how he got his scars in The Dark Knight, all of which are different, and therefore, probably made up. Well that must mean that Florence's story is also made up, and he trully is, as he said, gay and not British!
 * Tea is upset when she finds out the spoiler for the last Harry Potter book (she ships Harry/Hedwig), this is a good year before the book came out. Book comes out and Hedwig dies one chapter in. No wonder she was so upset...
 * Téa, a self-described shipper, is the one shown giving Marik's Millennium Item to Florence.
 * In episode 46 "Melvin'd" Bakura mentions that Zork got a job in "The sweet life of Zork and Cody". Four episodes prior Zack fell off the blimp and they needed a replacement.
 * In episode 36, Marik said that, if the fanfiction he's read is correct, the one Yugi loves most is Joey, and seemed shocked when Odion suggested that he loved Tea. Why? Because ever since he's a kid he's been a Yaoi Fanboy.
 * At first, Season Zero Abridged Episode 2 looks like it provides a straight up continuity error when Tristan angrily shouts at Yugi that his parents are dead. Then you remember the rest of the seasons are the 4Kids Censored Versions. In other words, they were were able to be alive during Episode 41 because Never Say "Die" was in effect.
 * I'm to believe Season Zero is an Alternate Universe, so it doesn't make a difference.

Fridge Horror
"Tristan: Your sister's the sexiest thing I've ever seen! I'm going to sleep with her!
 * Probably deliberate and Played for Laughs, but this exchange from Episode 25 definitely qualifies:

Joey: If you do, I'll kill you with my bare hands.

Tristan: You're just jealous!"

"Pharaoh: So Kaiba, are you ready to enter a world of pain?
 * In Season Zero 2 Kaiba comes across as an overly cheerful Stepford Smiler with hints of Empty Shell in there. It's hilarious until we see that in this continuity MOKUBA is the bad guy. What do you think "Emperor" Mokuba might have done to him to turn him into...that?
 * He even shows hints of being a masochist.

Kaiba: Sounds delightful."
