Ecclesiastes 7:3

7:3 Sorrow is better than laughter,

because sober reflection is good for the heart.

Ecclesiastes 10:19

10:19 Feasts are made for laughter,

and wine makes life merry,

but money is the answer for everything.

Ecclesiastes 7:6

7:6 For like the crackling of quick-burning thorns under a cooking pot,

so is the laughter of the fool.

This kind of folly also is useless.
