"The first principle is that you must not fool yourself, and you are the easiest person to fool."

"What I cannot create, I do not understand."

"The pleasure of finding things out is the most important thing."

"You don't have to know everything to do something."

"Babalú!"

"My greatest joy is making people smile."

"Laughter and love make a home."

"The best things in life are free."
