"Okay, so we all agree that until Christmas is over, we won't fight each other," Washington said, looking each Red and Blue in the eye. Well, as best as one could through helmets.
"Uh, yeah. Whatever," said Grif, though he didn't seem very interested.
"Everyone?" Wash said, louder, getting everyone's attention.
"Yeah, yes, fine," Everyone said at once, some more reluctant than others.
"Does it count if we kill our own teammates?" asked Sarge.
"Yes. You can't kill Grif."
Sarge muttered words no one cared to understand, and Caboose spoke, "What if we-"
"No," Wash said. "No team-killing. Period."
"But it could be a-"
"CABOOSE! When the guy says no team killing, he means it," Epsilon said. "I've already died enough times for this war. Most of them were because of you."
"What about an agonizing injury?" Sarge asked, "Can we do that?"
"No. No killing, no fighting, and no hurting of any kind until the holidays are over."
"Come on, Wash," Tucker said. "You gotta give us some freedom!"
"Okay. So you won't mind if I let Caboose kill you?" Washington said.
"Actually, the no killing thing sounds like a good idea. A great idea. The best idea I've ever heard," Tucker said, mind changed.
Washington looked satisfied. "That's what I thought."
Sarge spoke again, "What about a slight pinch, or maybe a push?"
"No!"
Tucker looked at Sarge, "Dude, just stop trying. It's not gonna happen."
".."
"What about-"
"No, Caboose. Not even if you give them orange juice after," Wash sighed, shaking his head. "Why can't you stop fighting for just a few days? It's not that hard!"
"We can't just stop fighting!" Sarge protested once more, "It's in our blood! They're Blue, we're Red, how can we not fight!?"
"Just-no. I'm leaving now, so don't start!" Wash ordered.
"How do you know we're not just gonna start killing each other as soon as you turn your back?" Grif inquired.
"Because if you do, I'll kill you."
"..."
2 hours later...
Washington stood by a pile of colorful dead bodies sitting around the canyon.
"Well, I warned them.."
