(MARTY CLEARS THROAT)

- I could repair it right away and have it for you tonight.

- Oh, tonight is the town festival. I wouldn't dream of having you work on my telescope during such an important occasion. You are planning on attending, aren't you?

- Well, actually, ma'am, I don't think...

- Yes, of course, the festival.

- Well, in that case, I'll see you this evening at the festival, Emmett. Mr. Eastwood.

- Ma'am.

- Thank you for taking care of my telescope.

- You're quite welcome.

- It's a nice telescope.

- Ladies and gentlemen, as mayor of Hill Valley, it gives me great pleasure to dedicate this clock to the people of Hill County!

- May it stand for all time!

- Tell me when, gentlemen.

- Three! Two! One! Now!
