Buford: "You owe me money, blacksmith."
Doc: "How do you figure?"
Buford: "My horse threw a shoe. Seein' as you was the one that done the shoeing, that makes you responsible."
Doc: "Well, since you never paid me for the job, I say that makes us even."
Buford: "Wrong! See, I was on my horse when it threw the shoe and I got throwed off! And that caused me to bust a perfectly good bottle of fine kentucky red eye. So the way I fugure it, blacksmith, you owe me five dollars for the whiskey and $75 for the horse."
Marty: "That's the $80."
Doc: "Look! If your horse threw a shoe, bring him back and I'll reshoe him!"
Buford: "I done shot that horse!"
Doc: "Well, that's your problem, Tannen!"
Buford: "Wrong! That's yours. So from now on you better be lookin' behind you when you walk. 'Cause one day you're gonna get a bullet in your back."
