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."

"Never underestimate the power of a good laugh."

"Laughter is the best medicine."

"A good laugh is the best medicine."

"Laughter is contagious and wonderful."
