Dogs laugh, but they laugh with their tails. What puts man in a higher state of evolution is that he has got his laugh on the right end. – Max Eastman
It is the ability to take a joke, not make one, that proves you have a sense of humor. – Max Eastman
For one seldom hears a genuine laugh nowadays, and much of the phraseology of laughter is a mere fashion of speech. There are many people whose sides have never ached from over-indulgence in the outward expression of mirth…. With some persons a wheeze or a chuckle is the utmost they can compass. – “Laughter,” in The Spectator for the week ending Saturday, January 19, 1889
