Marty: "Silence, Earthling! My name is Darth Vader. I am an extra-terrestrial from the planet Vulcan!"

Marty: "What made you change your mind, George?"

George: "Last night, Darth Vader came down from planet Vulcan, and told me that if I didn't take Lorraine out, that he'd melt my brain."

Marty: "Yeah, well, let's keep this brain melting stuff to ourselves, okay?"

George: "Oh, yeah. Yeah."
