So yeah, I got bored and did this instead of keeping up with my actual fanfiction.

"What do you think he's doing?"

The others shrugged.

"Who knows," Frank said, hunched over the mess table. "It's Leo."

"Yeah but," Piper paused, listening carefully. The faint sound of laughter came from the room opposite. "What is so funny?"

"I bet he's telling himself jokes," Annabeth complained. She had been moody since the Seven had decided to wake up early than was deemed 'wise', as she put it.

"Do we really wanna know?" Jason replied. "I think it's safer to just ignore him."

Percy frowned. "But if he's making himself laugh, and he knows the punchline… sounds like those are some good jokes."

Annabeth leaned over and punched his arm. "Shut up Seaweed Brain."

A distant crash, followed by the noise of someone falling over, before a scruffy little Latino boy came running in. He was breathing heavily, like someone who had just stopped laughing.

"Finally," Piper stared at the son of Hephaestus. "Leo, what were you doing?"

He paused, then grinned cheekily.

"Leo," Jason stood, then promptly slipped back into his chair.

Something about this was considerably funnier to Leo than everyone else, for he howled with laughter. He didn't stop for maybe another minute, and when he straightened to his, granted not very tall, but full height, there were tears in the corners of his eyes.

"Gods Jason. That wasn't very…graceful."

Everyone froze. They looked at each other in fear. No, no, no, no, no. Leo had not discovered puns. No he had not. With the air of a dad over dinner, about to launch into a story that would ruin everyone's morning, Leo pointed at Piper.

"Piper, what's that in your hair?"

His lip trembled as she reached up and touched her choppy brown locks.

"What? There's nothing…"

"It looks kinda dirty. Maybe you should…"

Piper's eyes widened.

"…McLean it."

Everyone started shouting.

"Leo shut up!" Hazel cried. "That's unbearable!"

One person wasn't calling for tomatoes and rotten fruit to be thrown at Leo. Percy sat in the corner trying to hide his laughter in his hand. Unfortunately, Annabeth noticed.

"Seriously?" The morning was not agreeing with her.

Percy stopped laughing, but couldn't wipe the grin from his face.

"Uh…" he was trapped.

"What's wrong Annabeth? Are you…?"

"Leo shut it right now unless you want an apple thrown somewhere apples don't go."

Leo stopped talking. Then grinned. "Why? You gonna…Chase me?"

Annabeth jumped from her seat and charged round the table as Leo took off screaming,

"I didn't mean it! I'm sorry! I'm too funny to die!"

His voice slowly turned to whelps and various bludgeoning noises which were quickly drowned by the son of Poseidon's roaring laughter.

Kinda inspired by that Office moment where Michael comes in with a list of ready-made 'That's what she said' jokes deliberately trying to start joking instead of waiting for good timing.

Also totally see this as canon Leo.

I promise I'll get back to writing Demi-Titan.
