There was a school play where an actor forgot his lines. Instead of panicking, he started making up the most hilarious lines on the spot. The whole audience was in stitches. It was a great example of how mistakes can turn into something really funny at school.
One funny moment is when Spiderman tries to imitate other superheroes' poses and fails spectacularly. Also, when he has comical misunderstandings with villains.
Once, my cat chased its own tail for a whole five minutes. It was so confused but also extremely hilarious. It spun around and around until it finally got dizzy and just plopped down on the floor.
For Doflamingo, you can focus on his flamboyant and unpredictable nature. Show his sadistic side in how he deals with enemies, but also explore his more vulnerable moments, like when his plans are thwarted. For Crocodile, emphasize his cool and calculating demeanor. Let his past failures fuel his actions in the fanfiction, like his determination to regain his lost status. Maybe show how Doflamingo's chaos sometimes clashes with Crocodile's order.
One character that would make for an interesting pairing with Doflamingo in a crossover fanfiction is Zoro. Zoro's strong sense of justice and his skills as a swordsman would clash with Doflamingo's devious ways. They could have epic sword battles, and Zoro might be the one to cut through Doflamingo's strings, both literally and metaphorically. Also, Nami could be paired with Doflamingo. Nami's intelligence and ability to manipulate situations for her own gain, although in a more positive way compared to Doflamingo, could lead to some really interesting interactions. She could try to outwit him in a game of wits.
I really like 'Doflamingo's Unseen Side'. It presents a different perspective on Doflamingo. It has a lot of action scenes and also explores his relationships with other characters in the One Piece universe in a unique way.
Once, my grandpa was looking for his glasses everywhere. He was turning the house upside down. After half an hour of frantic searching, he found them on his head. It was hilarious.
Once I was at a party and I was so excited to try this new dance move I'd just learned. But when I started, I slipped on a small puddle of spilled drink and landed right on my butt. Everyone stopped and stared for a moment, then burst out laughing, including me. It was so embarrassing yet funny at the same time.
There was a game where a Techies player set up a whole bunch of mines in the wrong area. Instead of trapping the enemy, he ended up blocking his own team's path to retreat. As the enemies chased them, his teammates were blowing up left and right on their own mines. It was really a comical sight. Everyone in the game was laughing about it, even the Techies player himself after realizing what he had done.
Well, once I had a Sim who was a bit clumsy. They were walking up the stairs to go to bed and tripped and rolled all the way back down. It was like a comedy skit. Another time, a Sim tried to dance at a party but ended up looking like they were having a seizure. It was so funny that the other Sims stopped what they were doing to watch.
