In the city, Ladybug landed and she saw Cat Noir, Eagle, and Uncanny seeing people laughing uncontrollably and in pain too.

Male citizen: Make it stop! Hahahahahaha.

Female citizen: My face hurts so much.

Ladybug: Why are they laughing?

Cat Noir: Looks like someone got the case of the giggles, but not the good kind.

Eagle: Guess Miss Jokes-a-lot is the root of the problem.

Joker: Ahh, the sound of laughter in the air. Nothing will ever spoil this moment. *Then, the Megakuma symbol appeared in her eyes. *

Shadow Moth: That's it, Joker! Now use your power on Ladybug and Cat Noir! Then once they're distracted by laughter, their miraculous will be mine for the taking!

Joker: Don't worry, Shadow Moth. You'll get those accessories you're obsessed with very soon. *The Megakuma symbol disappeared, and she smirked at them. * So, you four are going for some laughter?

Ladybug: You're not the comedic type.

Joker: Nonsense! People don't understand comedy or have a sense of humor. And I'm gonna make people believe that. Starting with Paris' favorite hero influencers.

Cat Noir: Sorry, miss. But the only one who can do jokes and puns is me.

Joker: Not for long you won't. I got something that might do the job. *She flipped through her book and found a joke. * How did the two cats end their fight? They hissed and made up. *She laughed evilly and threw her book out at them. *

Ladybug: Watch out! *They evaded the book flying and the book came back to Joker. *

Joker: Dang it, missed it.

Cat Noir: What's her deal?

Joker: What's the matter? Too scared to laugh at a joke? Well, I'll just force you to laugh at me, Joker! How did the barber win the race? He knew a shortcut! *She laughed evilly and threw her book out again. *

Eagle: Uncanny, watch out! Wings of Justice! *She flapped her arms, which made a gust of wind blow the book away. *

Joker: Hey! My book! *She flies after it. *

Uncanny: Thank you.

Ladybug: Her book? * Joker grabbed her book and scowled at them. *

Joker: That was a cruel joke, and I know cruel jokes. *She flies back towards them. *

Cat Noir: She's coming back! Hairball cannon! *He summoned a hairball cannon blaster and started firing out hairballs, Joker ducked and dodged the hairball blast. *

Joker: Yuck, hairballs. I hate hairballs and cats! *Cat Noir keeps firing out more hairballs at Joker, and then Ladybug flies up above Joker. *

Ladybug: Time to show you what I'm made of. *Her hands glowed red. * Ladybug swarm! *She summoned a swarm of Ladybugs, and they flew all over Joker, she shoos them away with her book. *

Joker: Your bugs are starting to "bug" me. No pun intended. Why couldn't the pony sing? Because she was a little hoarse. *She laughed evilly and threw her book out. *

Cat Noir: Not again. *They evaded the book flying, Uncanny flew up, opened her third eye, and shot out a laser beam, Joker evaded the laser beam. *

Joker: Seriously!? *Ladybug hovered next to Uncanny. *

Ladybug: She's forcing people to laugh by telling a joke from her book.

Eagle: I'll try to make them resist from laughing. Liberation! *Her talon pendant glows gold and she shoots out gold feathers at every lugging Parisian, they start running around freely. * There.

Cat Noir: What was your power again?

Eagle: I'm able to free people of any personality traits that hold them back from their full potential.

Cat Noir: Oh.

Joker: Hey! What did you do to them? Why aren't laughing at my jokes?

Eagle: They're free from your lame jokes.

Joker: Lame jokes!? Do you call my jokes lame???

Cat Noir: If she said it, then yes.

Joker: I'll show you lame jokes. *She opened her book, and she spotted a joke to use. *

Eagle: She's about to fire off another joke.

Cat Noir: Not this time, I'm afraid.

Joker: What's worse than finding a worm in your apple? Finding half a worm in your apple.

Eagle: Gross. *Joker laughed evilly, and she threw out her book. *

Uncanny: Get close to my forcefield. *She made an energy forcefield appear, the book hit the forcefield and Joker caught it, she growled and scowled. *

Ladybug: We gotta get that book from her. It must be where the Megakuma is hiding.

Uncanny: But what can we do? She's gonna make one of us laugh by force.

Eagle: She's packed and loaded!

Ladybug: And so are we. Lucky charm! *She threw her yo-yo up, a swarm of magical Ladybugs appeared, and a heckler book appeared. * A book about heckling?

Cat Noir: M'lady, you'll always be my biggest heckler. *Ladybug rolled her eyes at that. *

Joker: You're not gonna heckle a joke I'm about to tell you. Laugh at this one.

Ladybug: Laugh at this. Good luck kick!

Cat Noir: Claw shred! *Her leg glowed pink and she kicked out a pink energy beam from her leg Cat Noir's hands glowed black and he made claw shreds and fired it out to Joker. Joker was kicked in the gut and as the claw shreds pushed her back, she groaned angrily and the Megakuma appeared in her eyes again. *

Shadow Moth: Get up, Joker! You're so close to getting their miraculous!

Joker: I don't see you making much of an effort. You've given me a lame power. Do you think I'm the butt of the joke?

Shadow Moth: He who giveth can also taketh away!

Joker: Fine, fine. *The Megakuma disappeared on her face, and she scowled at them. *

Joker: You won't stay safe forever. I will make your ribs crack, your funny bone split, and your face hurt from my jokes.

Cat Noir: I don't want any of that to happen. *Ladybug looked around and she saw the Heckler book, Cat Noir, Eagle, Uncanny, and Joker's book. *

Ladybug: (Who says comedy shouldn't have a little negative feedback.) I know how we can beat Joker. We heckle her saying her joke telling is terrible.

Cat Noir: Hope she'll take negativity well, unlike all comedians. *Uncanny opened her forcefield, Joker lowered her book and she smirked. *

Joker: So, begging for more jokes, huh? Well, I can help you with that. *She goes through her joke book. * Here's a really good one. What's the difference between beer nuts and deer nuts? One's a dollar 99, and the other one's under a buck. *She laughed evilly and threw the book out, Eagle summoned her defense shield and blocked off the book. * Here's one: Why can't you send a duck to space? Because the bill would be astronomical! *She laughed evilly again. * Try to dodge this joke! *She flew up and threw the book at them, they evaded the joke book, Uncanny shot out rocket missiles at Joker, but she evaded them as they exploded. *

Eagle: A 5-year-old can tell a better joke than you. *Joker gritted her teeth angrily. *

Joker: Why can't you just understand comedy!!! Fine, I got something that's even better. *She flipped through a few pages and found the perfect joke. * What did the worker at the rubber band factory say when he was fired? Oh, snap. *She laughed evilly and threw the book out at them; they evaded the book again. *

Uncanny: By that logic, your comedic way is out of touch, but your material needs improvement.

Joker: My material does not need to be improved; you people have no sense of humor whatsoever.

Cat Noir: Since you like throwing your joke book, try a better joke but you claim to be a comedian villain, you don't have the guts to do it, do you?

Joker: Ph, I'll show you who has guts. I'll show you all! *She flipped through the book again and saw a joke in it. * Why do teenage girls travel in odd-numbered groups? Because they can't even. This will get you into a sense of humor! *She threw the book out at them. *

Cat Noir: Time for a little page-turner. Cataclysm! *His hand turned the book into coal and it shattered into pieces, and then the Megakuma flew out. *

Joker: No, my book!

Eagle: Now that the book is destroyed, time to cancel out my power. Cool down! *The gold feathers disappeared, and everyone started laughing again. *

Ladybug: No more evil-doing for you, little Akuma. *She swiped open her yo-yo and started twirling her yo-yo. * Time to de-evilize! *She then threw it out, caught the Megakuma, and closed her yo-yo. * Gotcha! *She opened her yo-yo and freed the Butterfly. * Bye-bye, little Butterfly. *She picked up the heckler book and threw it up in the air. * Miraculous Ladybug! *People stopped laughing and felt their faces from all the laughing, and Joker changed back to Lisa. She felt her head and moaned, she looked around and was confused about what was going on. *

Ladybug, Cat Noir, Eagle, and Uncanny: Pound it!

Lisa: What happened?

Ladybug: You were akumatized, forcing people to laugh at your jokes.

Lisa: I did? Sorry. Chloe said that I don't have what it takes to be a comedian and my jokes telling is not funny. Then she stomped on the book my uncle gave her. Maybe she's right for once.

Eagle: (That brat did it again.) *Then, Ladybug swiped open her yo-yo and pulled out a magical charm for Lisa. *

Ladybug: Lisa, this magical charm will protect you from being Shadow Moth's victim again. Don't let anyone tell you what you can or can't do, and don't let them bring your spirit down on what you love to do the most. *Lisa looked at the magical charm and grinned. *

Lisa: Thank you, Ladybug. I promise. *She gets up and walks away. In Shadow Moth's Lair, Shadow Moth groaned angrily. *

Shadow Moth: Hmm. I guess Joker's defeat means I won't get the last laugh this time Ladybug. But mark my words, the time will come when I do defeat you and my wish will come true! *The window starts to close. *
