Quote by Bruce Banner (Age of Ultron)

"I'm not a hero. I'm a scientist."

"The problem isn't that we need to be smarter. The problem is that we need to be better."

"I can't control it. When I get angry, everything changes."

"We create our own demons."

"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."
