I was having dinner with Garry Kasparov and there was a check tablecloth. It took him two hours to pass me the salt.
A group of chess enthusiasts checked into a hotel and were standing in the lobby discussing their recent tournament victories. After about an hour, the manager came out of the office and asked them to disperse. "But why?" they asked, as they moved off. "because," he said "I can't stand chess nuts boasting in an open foyer."
