The human race has only one really effective weapon, and that is laughter.

The only way to survive is to find some humor in the situation.
I think the next best thing to solving a problem is finding some humor in it.

Life is like a sewer: what you get out of it depends on what you put into it.
Humor is just another defense against the universe.
Against the assault of laughter, nothing can stand.
Laughter is the shortest distance between two people.

The secret source of humor is not joy but sorrow; there is no humor in heaven.
