Quote by Doc Brown

"This is heavy."

"There's that word again, 'heavy.' Is there something wrong with the Earth's gravitational pull in the future?"

"Great Scott!"

"If my calculations are correct, when this baby hits eighty-eight miles per hour, you're gonna see some serious shit."

"Hard work never killed anybody."

"Work with purpose and integrity."

"Hard work pays off in the end."

"A man's gotta do what a man's gotta do."
