Marty McFly

— Nobody calls me yellow.
— Then let's finish it. Right now.
— Not now, Buford. Marshal's got our guns.
— Like I said, we'll finish this tomorrow!
— Tomorrow we're robbing the Pine City stage.
— What about Monday? We doing anything Monday?
— Monday would be fine. You can kill him on Monday.

«And so, Marty, I now say farewell|and wish you Godspeed. You've been a good, kind, and loyal friend to me... and you made a real difference in my life. I will always treasure our relationship and think of you with fond memories warm feelings and a special place in my heart. Your friend in time, Doc Emmett L. Brown. September 1, 1885.»
— I never knew I could write anything so touching.
— I know, it's beautiful.

— I'm not one to pry into a man's personal affairs but exactly how is it you came to be way out here without a horse, or boots, or a hat?
— Well, my horse broke down and a bear ate my boots and I just forgot my hat.
— How could you forget a thing like your hat?

That's William? William Sean McFly, the first of our family to be born in America.

— When?
— High noon?
— Noon? I do my killing before breakfast. 7:00!
— 8:00. I do my killing after breakfast.

— You can have this brand-new Colt Peacemaker and gun belt, free of charge.
— Free?
— I want everybody to know the gun that shot Buford Tannen was a Colt Peacemaker!
— No problem. Thanks a lot.
— Of course, if you lose, I'm taking it back.

— It blew the fuel injection manifold. Strong stuff, all right. It will take me a month to rebuild it.
— A month? Doc, you're gonna get shot on Monday.
— I know. I know. I know. I wish... Wait. I've got it. We can simply roll it... down a steep hill. Oh. We'd never find a smooth enough surface. Unless... Of course. Ice. We'll wait until winter
when the lake freezes over.
— Winter? Doc, what are you... talking about? Monday. It's three days away.

— Hey, «Frisbie». Far out.
— What was the meaning of that?
— It was right in front of him.
