As relayed by Stephen Bainbridge:

One day shortly after the Second World War ended, Winston Churchill and Labour Party Prime Minister Clement Attlee encountered one another at the urinal trough in the House of Common’s men’s washroom. Attlee arrived first. When Churchill arrived, he stood as far away from him as possible. Attlee said, “Feeling standoffish today, are we, Winston?” Churchill said: “That’s right. Every time you see something big, you want to nationalize it.”
