"Great Scott!"
"MARTY! We went too far into the future!"
-Doc
"You're tellin me, Doc!"
"Does the world come to an end??"
-Marty
"It seems we've entered in to a post-apocalyptic time period!"
"But where are we?"
"Let me check the Flux Capacitor..."
-Doc
"DOC! LOOK! We only went to the year 2015!"
-Marty
"There's no way the world has fallen apart this quickly."
"We only went 40 years into the future!"
-Doc
"Wow man... This is heavy!"
"So if the whole world doesn't look like this, where are we?"
"And why is this place destroyed?"
-Marty
"That's an excellent question Marty!"
"I wonder how we could figure out such a thing?"
-Doc
"Look! There's some people out there!"
"Hey guys! We got a question for ya!"
-Marty
"Does anyone know how to find the history of a place??"
"What are some good methods in obtaining past information of a location?"
-Doc
(But seriously...)
