SCROOGE'S NEPHEW
If you should happen, by any unlikely chance, to know a man more blessed in a laugh than Scrooge's nephew, all I can say is, I should like to know him too. ... It is a fair, even-handed, noble adjustment of things, that while there is infection in disease and sorrow, there is nothing in the world so irresistibly contagious as laughter and good-humour. When Scrooge's nephew laughed in this way--holding his sides, rolling his head, and twisting his face into the most extravagant contortions--Scrooge's niece, by marriage, laughed as heartily as he. ... 'He's a comical old fellow,' said Scrooge's nephew, 'that's the truth; and not so pleasant as he might be. ... But being thoroughly good-natured, and not much caring what they laughed at, so that they laughed at any rate, he encouraged them in their merriment, and passed the bottle, joyously.
