laugher

When people ask me how I find the strength to laugh now, I reply that I am a professional laugher.

There is, then, your discontented cynical laugher, who makes a mask of mirth to conceal the venom of his mind.

If a man is not a laugher by nature, he had better let it alone.

Certainly I am a great laugher, and it is better to laugh too much than too little.

(if you will pardon a new word,) but there is some difference between a laugher and a critic.

A great essayist has defined laughter as a "feeling of superiority in the laugher over the object laughed at."
