(Marty is about to go out of the back door when he chances upon his future parents)

Lorraine!

Marty, that was very interesting music.

Yeah.

I hope you don't mind, but George asked if he could take me home.

Well, that's great! (Touches Lorraine's chin with his finger) I had a feeling about you two.

(Blushes)

I have a feeling too...

Listen, I got to go, but I just want to tell you that it's been...educational.

(Shakes Marty's hand)

Marty, I want to thank you for all your good advice. I'll never forget it.

Marty, will we ever see you again?

I guarantee it. Well, good luck you guys. (Walks away, and turns back) Oh, and one other thing, if you guys ever have kids (Lorraine is agape with surprise), and one of them, when he's eight years old accidentally sets fire to the living room rug? Go easy on him.

(as soon as Marty is out of sight)

Marty... such a nice name.
