"Sapere aude! Dare to know! Have courage to use your own understanding."

"Two things awe me most: the starry sky above and the moral law within."

"Happiness is not an ideal of reason but of imagination."

"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."
