Laughter is the sensation of feeling good all over, and showing it principally in one spot.
He who laughs, lasts.

A joke is an epigram on the death of a feeling.
One loses so many laughs by not laughing at oneself.
You can pretend to be serious, but you can't pretend to be witty.

The love of truth lies at the root of much humour.
