Lorraine Baines: Marty? Why are you so nervous? Marty McFly: Lorraine. Have you ever been in a situation where you knew you had to act a certain way, but when you got there, you didn't know if you could go through with it? Lorraine Baines: You mean like how you're supposed to act on a first date? Marty McFly: Sort of. Lorraine Baines: I think I know exactly what you mean. You know what I do in those situations? Marty McFly: You do? What? Lorraine Baines: I don't worry. Lorraine Baines: Lorraine Baines: This is all wrong. I don't know what it is. But when I kiss you, it's like I'm kissing... my brother. I guess that doesn't make any sense, does it? Marty McFly: Believe me, it makes perfect sense.
