Quote by Dr. Emmett Brown

"Great Scott!"

"This is heavy."

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

"If my calculations are correct, when this baby hits 88 miles per hour, you're gonna see some serious shit."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
