Quote by Walter White

"I am the one who knocks."

"You asked me if I was in the meth business or the money business. Neither. I'm in the empire business."

"A man provides. And he does it even when he's not appreciated or respected or loved."

"I did it for me. I liked it."

"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."
