Stalin was a keen and accomplished billiards player, and collected watches. He also enjoyed practical jokes; he for instance would place a tomato on the seat of Politburo members and wait for them to sit on it. When at social events, he encouraged singing, as well as alcohol consumption; he hoped that others would drunkenly reveal their secrets to him. As an infant, Stalin displayed a love of flowers, and later in life he became a keen gardener. His Volynskoe suburb had a park, with Stalin devoting much attention to its agricultural activities.
