There are plenty of stories of eccentric British judges, whose asides and obiter dicta from the bench are celebrated in literature and legal anecdotage. One instance from many should suffice. In one of his stories, that incomparable wit, G K Chesterton, has a delightfully unconventional judge telling a young man in the dock. "I am sentencing you to six months imprisonment as the law requires, despite my God-given conviction that what you need is six weeks in the countryside."LINK
Certainly, tolerance of folly and a sense of humour would not come amiss in judges who have to endure a good deal of nonsensical casuistry in the course of their duties.
As a father of young children I find "tolerance of folly and a sense of humour" necessary for sanity.
