Stella Baines
- [Stella Baines is Marty's future grandmother]
- Stella Baines: You know, Marty, you look so familiar to me. Do I know your mother?
- Marty McFly: [turning to look at Lorraine, his mother in the future] Yeah, I think maybe you do...
- [Lorraine's parents are talking about Marty McFly, Lorraine's future son]
- Stella Baines: He's a very strange young man.
- Sam Baines: He's an idiot. Comes from upbringing. His parents are probably idiots, too. Lorraine, you ever have a kid who acts that way, I'll disown you.
- Lorraine Baines: It's our first television set. Dad just picked it up today. Do you have a television?
- Marty McFly: Well, yeah. You know we have... two of them.
- Milton Baines: Wow! You must be rich.
- Stella Baines: Oh, honey, he's teasing you. Nobody has two television sets.
- Stella Baines: Joey just loves being in his playpen. He cries whenever we take him out, so we just leave him in there all the time.
- Lorraine Baines: That's a big bruise you have there.
- Marty McFly: [backing away, he falls off the bed] Ahhh!
- Stella Baines: [hearing the noise] Lorraine, are you up there?
- Lorraine Baines: Oh, my god. It's my mother! Quick! Put your pants back on!
- Stella Baines: So, tell me, Marty, how long have you been in port?
- Marty McFly: Excuse me?
- Stella Baines: Ah, I guessed you're a sailor. I think that's why you wear that life preserver.
- Marty McFly: Uh, Coast Guard.
