Doc Holliday and Wyatt Earp were drinking whiskey and swapping tales. Doc had one of his tubercular coughing fits.

“Say there, Doc. You wanna quit coughin’ my way”, Earp told Doc.

“What? Oh, sorry, Wyatt. You know, I probably killed off more guys this way than gunnin’ them down. Course, you may have done a few in yourself with that breath of yours. Whew, you smell like you eat your food twice”.

“Doc, ain’t no man but you could say that to me and live.”

“Well, Wyatt, seeing as how I ain’t going to live too much longer no way, it don’t really matter much”.

“Doc, maybe you just have a bad cold and can’t shake it off. Ever think a that?”

“Wyatt, I see what I toss up when I cough. It’s enough to make you throw up, which I do. That makes me gag and more mucus -. You alright, Wyatt?”.

“Doc, let’s go kill someone. Let's try the OK Corral first. I don’t like the way this conversation’s going”.

“Okay, let me get my shotgun.”

“Why do you use that shotgun?”

“Wyatt, if I go to coughing up mucus and tossin’ and gaggin’, I want to be sure it don't matter where I shoot.”
