- I don't know. Are you sure this stuff is authentic?

- Of course!

- Haven't you ever seen a Western?

- Yeah, I have, Doc. And Clint Eastwood never wore anything like this.

- Clint who?

- That's right. You haven't heard of him yet.

- Marty, you have to wear the boots. You can't wear those futuristic things back in 1885. You shouldn't even be wearing them here in 1955.

- All right, Doc. Look, as soon as I get there, I'll put them on. I promise.

- Okay. I think we're about ready. I put gas in the tank.

- Your future clothes are packed.

- Just in case, fresh batteries for your walkie-talkies.

- Oh! What about that floating device?

- Hoverboard. All right.

- You know, Doc, it's gonna be a hell of a long walk back to Hill Valley from here.

- It's still the safest plan. After all, we can't risk sending you back into a populated area, or to a spot that's geographically unknown.
