One Piece:The Great Deck
It was all Usopp's fault.
The sea was calm and the Going Sunny was peacefully drifting along, so the sharpshooter was keeping their rubber captain, Luffy, entertained while Sanji made lunch. He'd decided truth or dare would be fun, a childhood game Luffy didn't seem to know, but he had enjoyed with his little trio of kid pirates back in the day. Of course, Luffy being Luffy was only interested in the dares. Knowing their captain was pretty much fearless…or just stupid sometimes, he thought extra hard to come up with some fun ones.
After Luffy dared him to eat a mushroom (terrifying), which he had to try to sneak out of Sanji's kitchen (far more terrifying), he was ready to get even. Stealing said cook's food after agreeing to keep their hungry captain entertained was definitely not a welcome move, and he still had the bruises from Sanji's hard-as-hell kicks to prove it.
"I dare you…to deck… Zoro," Usopp grinned. This would be epic. Of all the crew, the ladies were clearly off limits, Brook and Franky probably honestly wouldn't care or would just laugh it off, Chopper just…no, and Sanji for two reasons. First, he usually wore a belt so that would be too tricky, and secondly he wasn't THAT mad at Luffy.
"We're on the deck," Luffy blinked. Usopp stared at him for a few minutes.
"No, deck him. Like, run up to him and pull down his pants," Usopp elaborated for him.
"Why would I want to pull down his pants?"
"Trust me, it's a joke. It's funny," Usopp didn't add that it would probably be the last thing Luffy did.
"Zoro's underpants are funny?"
"No. Just- I dare you. Come on, are you chicken?" he teased their captain.
"Never!" Luffy started sneaking up on Zoro, surprisingly well considering how stealth wasn't one of his main attributes.
Sanji had took a moment from lunch preparation to take a smoke break, so naturally, Zoro decided to harass their cook after having a long nap and feeling particularly bored on such a nice day. Sometimes a pirate's life was exciting. On days such as these, they got into mischief when there was little else to do. The two were snapping insults at each other when Luffy reached range to stretch his long rubbery arms towards the unsuspecting swordsman. Raising one finger to his lips he motioned a 'keep quiet' signal to Sanji over Zoro's back. The cook paused. Stared. A clear 'what the fuck' expression on his face. Usopp glanced around quickly. The rest of his crewmates were strewn lounging about, the girls for instance sunbathing with books in hand, Brook playing a low melody while Chopper sleepily rested against him. Franky was drinking a cola. But now, they all were looking with mildly curious eyes towards a scene which was sure to unfold.
"What are you staring at me like that for?" Zoro glared at the cook momentarily before realizing he wasn't actually looking at him, and swiveled.
Luffy, seeing this was his moment to act before Zoro knew well enough to stay out of reach, whipped the swordman's pants down right as he turned.
Of course he'd chosen today to go commando.
Nami screamed, Robin hid her face with her book (though Usopp was pretty sure he saw her laughing quietly), Brook quickly covered Chopper's eyes (unfortunately he couldn't close his own…yohoho skull joke), and Franky did a spit take.
Blood sprayed from Sanji's nose. Luffy himself burst out into cackling laughter as he took off running, while Zoro face-planted trying to run after him. Before pulling his pants up. Usopp decided now would be a very good time to hide before they figured out exactly whose idea this was.
