'Laughter' in the Bible

I said of laughter, It is mad: and of mirth, What doeth it?

Sorrow is better than laughter: for by the sadness of the countenance the heart is made better.

For as the crackling of thorns under a pot, so is the laughter of the fool: this also is vanity.

A feast is made for laughter, and wine maketh merry: but money answereth all things.
