A jest breaks no bones.

A joke is at most a temporary rebellion against virtue, and its aim is not to degrade the human being but to remind him that he is already degraded.

A difference of taste in jokes is a great strain on the affections.

I said of laughter, “It is mad,” and of pleasure, “What use is it?”

Laughter almost ever cometh of things most disproportioned to ourselves and nature. Laughter hath only a scornful tickling.
