Bermuda Triangle
Luffy checked over his shoulder. At last, at long, long last, the guardian had left its prize unattended and ripe for the taking. His arms stretched lustily forwards…
Which is precisely when Nami brained him with her heavy metal pole. Luffy slammed into the deck face-first, utterly confused.
"Not the oranges!" Nami shrieked, "The oranges are sacred!"
"But Nami," Luffy whined, "I'm hungry…"
The other three teenage males aboard were silently cheering him on.
"Shitty cook," Zoro muttered under his breath, which is to say he half-shouted so that Sanji, who was on the other side of the boat, could hear him.
"What am I supposed to cook?" Sanji exploded, "We didn't have money for food because you drank it all!"
"Tch. Blaming others for your own incompetence…" Zoro sniffed haughtily. It was, all in all, a very un-Zoro-like thing to do, but going by the veins popping from Sanji's forehead, had the desired effect.
"Once," Usopp began abruptly and arrestingly, "I seduced a thousand, no, a million mermaids, whilst stranded on a deserted island. I mean to say, I was stranded by choice. Actually, I was on vacation. Regardless, the hoards of mermaids fed me and sheltered me and I had sex with them. All of them! THREE TI—"
Zoro pushed him over the rail.
Luffy picked his head over the railing, delightedly watching his sharp shooter burble and thrash in the ocean's warm waters. "Usopp? Oh, good! While you're down there, would you mind asking your mermaids for some meat?"
"O-Oh, sure!" Usopp laughed like a madman. Zoro leaned over the rail, looking unimpressed.
"Huh. You need a rope or something?"
"Of course not! I can fly!"
"Really?" Nami drew up alongside Zoro and Luffy, her voice fairly dripping with sarcasm. Sanji swooned.
"Ah! So refreshingly witty! So divinely inspired!"
Zoro sneered at him, "Why, thank you."
Whatever Sanji was going to say to this was forever lost, as a Sea King of truly massive proportions surged up from the sea, it's great mouth open and bearing down on Usopp. His and Nami's twin screams could be heard for miles.
"NAMI! SAVE ME!"
"KILL IT!" Nami yelled back, utterly abandoning poor Usopp.
"You kill it! I'm about to be eaten!"
"I appreciate your sacrifice! Goodbye!"
"YOU—!"
"Dinner!" Luffy cheered, and then he, Zoro and Sanji, set upon it.
