Yu-Gi-Oh! GX/Funny

"Adrian: I activate two of my face-downs!
 * From the Gag Dub dub:

Chazz: But how?

Adrian: Easy -- I just call out their names dramatically, and they pop up. Haven't you played this game before?"

"Chazz: (thinking) There's only room for one spoiled rich kid at this school, and that's me. (Aloud) ENOUGH! Leave me alone! Who cares if he's richer than me? And so what if he's more powerful? I'm really good at playing card games! And that's what life is really all about, anyway! (panting)
 * His musings on Adrian Gecko

Ojama Yellow: Take it easy, boss! You'll pop a blood vessel!

Chazz: Who cares?! I'll just buy a new one! Do you hear me, Adrian Gecko? By the way...what kind of a name is Adrian Gecko, anyway? I've got a much cooler name! AND UNLIKE YOU, I'VE ALSO GOT MY OWN Catch Phrase! CHAZZ IT UP!!!"

"Jim: 'Kangaroos have pouches because they're marsupials'. Me and Karen are gonna go have a nap."
 * Episode 108. Amon is getting all philosophical about duelling to Jim, quoting 'cogito ergo sum' in relation to the dis-duels which spell trouble for those aren't Hot-Blooded Idiot Heroes. Jim's inspired response?

""I didn't know he was a doctor."
 * Chazz and Adrian are full of these. "The sooner I beat you, the less bad dialogue I have to hear!"
 * It's official. Little Kuriboh is writing for Yu-Gi-Oh! GX.
 * "They've been dueling all night." Sure...
 * Chazz telling his new opponent, "Look, kid, you're an obnoxious little punk. And I can respect that..."
 * There's at least one per season. Season one: Jaden is still in the infirmary after his previous duel, and everyone is standing around discussing what to do since Camula just defeated Crowler. Jaden tries to get up and say that he'll take care of her, but Chazz reminds him that he can barely stand, casually pulls the sheet over him, and to further emphasize that Jaden is in no condition to duel, Jaden cannot get out from under the sheet! Then for extra giggle points, Chazz tells him to quiet down, and Jaden meekly says, "Okay," and does.
 * The second season moment also involves Jaden, while he's wandering around the island trying to find his way to the school building. There is a sign that clearly points the way. The buildings are visible beyond the sign. Jaden cheerfully stalks off in the entirely wrong direction. The sign sweat drops.
 * A few seconds later, it face faults, it's utterly hilarious!
 * For season three, we turn to Jim for a quick giggle moment in a very dark part of the story. He and O'Brien, along with two new friends just made, arrive at a village that's under attack by Haou's forces. Total Defense Shogun, known as Burgandy, is defending his village from those forces. Jim rushes up declaring that he will help, but Burgandy takes this the entirely wrong way, believes that Jim works for Haou, and brings his sword smashing down on Jim's head, just as the old man Jim was with tells him that this is a friend. Burgandy gets the most amazing wtf look on his face and is all "I hit an ally?" just as Jim goes "ouch" and falls over unconscious.
 * Season four, we're back with Jaden, and I will say this in just two words: Pharaoh's fleas.
 * Three more words: Daitokuji-sensei. Toilet.
 * The dub gets major points for never shying away from the most obvious humor at Crowler's expense:

"I didn't know he was even a dude.""

"Hassleberry: Duel Spirits? What kind of fool do you take me for?
 * Fubuki arms his Bronze Warrior with The Ultimate Stage Costume, giving it 3000 more ATK points. Nice move. Then, he tries to attack with it, only to find that the costume is too big and his monster can't fight in it.
 * The above scene is topped off when said monster attacks Asuka with its ATK back to normal. The monsters chosen method of attack? Smacking her in the back of the head. Dub Alexis tops it off by asking "What's your problem?"
 * When the Toy Solders attack Crowler directly, by shooting him below the belt.
 * In third season dub, Ojama Yellow's voice dropping several octaves when he greets a trio of female duel spirits.
 * An early one: Alexis being called the Obelisk Blue Fairy. Syrus's immediately pictures Obelisk with fairy wings.
 * From the Manga: Bastion duels Jaden so he can get Alexis' number. When Jaden just offers to give it to him, Bastion says that his pride prevents it leading Syrus to point out that he's still not proud enough to just ask her himself.
 * After Aster explains Duel Spirits in the dub.

Aster: I don't think you want me to answer that, Hassleberry."

"Crowler: He seems familiar.
 * Bonapart sums up Jessie/Johan perfectly in the dub:

Bonapart: That's because he's Jaden with a southern accent."

"Syrus: Something's not right about him.
 * About Professor Viper after he gives of an Evil Laugh

Hassleberry: What gave him away? The creepy laugh or the evil music?"

"Jessie: I don't know what's worse, a guy who thinks he's a dinosaur or a guy who thinks he's a drill sergeant."
 * After Hassleberry returns from his primitive state in the dub

"Jaden: Chaz, if you have a plan, now would be a good time to activate it.
 * Adrian Gecko: I wonder why everyone thinks out loud at this school
 * Another gem from Adrian and Chazz's duel:

Chazz: I end my turn.

Adrian: Some plan."

"Chazz: Listen you Al Roker wannabe..."
 * And later:

"Alexis: Laugh it up, bro...'cause I'm about have the last laugh!"
 * Professor Viper: "Can't I plot evil in peace?"
 * Many moments in the duel between Alexis and Atticus.

"Mask of Laughter: "Draw Bomb"...when your opponent draws a card, they...take one thousand damage!?! THAT'S NOT FUNNY!! *KABOOM!!!* (Life Point meter rolls to 0 and razzes.)"
 * O'Brien gets one that also doubles as an Awesome Moment in his duel with the Mask of Laughter. After MoL spends a moment laughing to himself about how foolish O'Brien was not to finish him off last turn (instead leaving him with 1000 Life Points) and going into detail about how he'll win this turn, he draws his card...only to see his opponent walking away. With an activated trap card, which he then reads to himself.

"Aster: ! Stop laughing and help me would you!?"
 * Yugioh GX Tag Force 2, while not in canon with the anime, does have a genuinely funny moment at the end of Aster's story. After Aster comments that Jaden might find it hard to go pro with his current scores in the academy, Jaden goes a little study nuts, quickly going to ask Bastion for his study tips while the story ties itself up. The funny part is when Jaden decides that it'd be faster to learn from a pro, namely Aster, quickly and pretty much forcing him to help and comes up with a funny line... and given Aster's not so good AI, this makes up for that.

"Hasseleberry: Never trust three mutants in bikini briefs."
 * For those of you wondering, picture it in your head, Jaden is dragging Aster off forcibly by his arm to help Jaden study... and you, his tag partner, just stand back and laugh at him.
 * When Jaden is dueling the Light of Ruin-possessed Chazz, and the Ojamas eventually betray Jaden.

"Syrus: Jaden, I carried that water for three whole episodes."
 * When Syrus brings Jaden a bucket of drinking water in one episode and Jaden proceeds to dump it all over himself, an annoyed Syrus gives us this gem:
