The thinkers of the world should by rights be guardians of the world's mirth.
Ingrid Seward
As the Supreme Governor of the Church of England, the Queen feels she cannot be seen to smile in church - and her natural reaction is to combat mirth by putting on a stern face.
James Thurber
The appreciative smile, the chuckle, the soundless mirth, so important to the success of comedy, cannot be understood unless one sits among the audience and feels the warmth created by the quality of laughter that the audience takes home with it.
Joseph Addison
If we may believe our logicians, man is distinguished from all other creatures by the faculty of laughter. He has a heart capable of mirth, and naturally disposed to it.
