In his "Scotch Reminiscences" Dean Ramsay relates that a certain ruling
elder, by the name of David, was well known in the district as a very
shrewd and ready-witted man. He received visits from many people who
liked a banter or were fond of a good joke. One day three young
theological students called on the old man, intending to sharpen their
wits upon him and have some fun at his expense.
