I have the satiric temperament: when I am laughing at anyone I am generally rather amusing, but when I am praising anyone, I am always deadly dull.

(All the coaches shall be scrap and rust and all the men and women laughing in the diners and sleepers shall pass to ashes.) I ask a man in the smoker where he isgoing and he answers: 'Omaha'.

  Chicago Poems,'Limited'.

There is continual spring, and harvest there Continual, both meeting at one time: For both the boughs do laughing blossoms bear, And with fresh colours deck the wanton prime, And eke attonce the heavy trees they climb, Which seem to labour under their fruits load: The whiles the joyous birds make their pastime Amongst the shady leaves, their sweet above, And their true loves without suspicion tell abroad.

  Of the Garden of Adonis. The Faerie Queen, bk.3, canto 6, stanza 42.

If I laugh on that particular day I become so filled with Laughing Gas that I simply can't keep on the ground. Even if I smile it happens.The first funny thought, and I'm up like a balloon. And until I can thinkof something serious I can't get down again.
