From a column by Allan Fotheringham, “The mouse, the elephant and the crackers in the bed”, Globe and Mail, January 27, 2001, p. A9:
John Kennedy could not stand John Diefenbaker. Instructed to do the ritual tree-planting ceremony at Rideau Hall in 1961, he shovelled in a good dozen tosses of dirt in an attempt at macho competition to show up his much older adversary. He reinjured his wartime PT boat back problem, and had to retire to a rocking chair at every opportunity. Richard Nixon was required to do the same stale tree trick at Rideau Hall. The tree died.
