If every word I said could make you laugh, I'd talk forever...

He who laughs best to-day, will also laugh last.

Ten times must you laugh during the day, and be cheerful; otherwise your stomach, the father of affliction, will disturb you in the night.

Not by wrath, but by laughter, do we kill. Come, let us kill the spirit of gravity!

And let that day be lost to us on which we did not dance once! And let that wisdom be false to us that brought no laughter with it!

The joke loses everything when the joker laughs himself.
