That'll shoot the fleas off a dog's back at five hundred yards, Tannen! And it's pointed straight at your head!
Doc Brown
So you're my great-grandfather. The first McFly born in America. And you peed on me.
Marty McFly
I'll hunt you and shoot you down like a duck!
Buford "Mad Dog" Tannen
Copernicus, what is it? You look like you have seen a ghost.
Doc
Here lies Emmett Brown. Died September 7th, 1885. Shot in the back by Buford Tannen over a matter of 80 dollars. Tombstone erected in memory by his beloved Clara.
Epitaph
My horse threw a shoe. And seeing as you was the one who done the shoeing, I say that makes you responsible.
Tannen
Well, since you never paid me for that job, I say that makes us even!
Brown
Wrong! See I was on that horse when it threw the shoe and I got throwed off! And that caused me to bust a perfectly good bottle of Kentucky red-eye. So, the way I figured it, blacksmith, you owe me five dollars for the whiskey and 75 dollars for the horse.
Tannen
Look! If your horse threw a shoe, bring him back an I'll re-shoe him!
Brown
Marty, you're going to have to do something about those clothes. You walk around town dressed like that, you're liable to get shot.
Doc Brown
Clayton Ravine was named after a school teacher. They say she fell in there a hundred years ago.
Marty
Every kid in school knows that story 'cause we all have teachers we'd like to see fall into the ravine.
Marty
In the future, we don't need horses. We have motorized carriages called automobiles.
Doc Brown
If everybody's got one of these auto-whats-its, does anybody walk or run any more?
Barfly 3
Of course we run, but for recreation. For fun.
Doc Brown
