I got this random idea and decided to run with it... Let me know what you think!

The woods were quiet apart from the shuffling steps and low growls of a lone walker, wandering mindlessly through the trees, gnashing its teeth, decayed flesh beginning to fall away from its bones-

There was the twin sounds of a bowstring and a silenced bullet and the walker dropped dead. Again.

A rough looking man with long hair hanging in his eyes and no sleeves stepped from his hiding place carrying a crossbow, already loaded in preparation for another shot. "That one's mine," he announced, going to fetch his bolt from the corpse.

"The fuck it is," another man replied as he came out into the open, both cleaner and better groomed, holding a gun and speaking with an Irish accent. "'Twas my shot, an' ye fuckin' know it, Dixon."

"Like hell, MacManus! My bolt hit first, you took too damn long praying for the son of a bitch! You ain't shot shit first in weeks!"

"Ye're so full a shit! I got the fucker three days ago that nearly bit ye when ye were too fuckin' busy playin' Robin Hood an' tryin' ta reload yer stupid fuckin' bow! I saved yer sorry ass!"

"Then we're even for when that one came up on ya and you were so drunk you couldn't handle your own knife and dropped the damn thing, you asshole!"

"Would ye both keep yer fuckin' voices down?" a third man asked, dark blond hair sticking up in all directions and also speaking with an accent. "Ye'll draw every undead fucker for miles, ye keep this shit up."

"Connor, tell him," the second man urged, "I killed that one, he's lost it if he thinks different."

"I don't think shit, it's a fact."

"Ye've both lost it, now let's keep moving, for fuck's sake."

They moved ahead, still arguing, and Connor shook his head in irritation. Between his hotheaded twin and the combative redneck, they'd be lucky if he didn't lose his fucking marbles and kill them both before walkers did.

I've got a few ideas, but if you've got a thought or two for some trouble the boys can get into, let me know and we'll see what we can make happen. :)
