"One morning I noticed there was an envelope with a typed address on it. No stamp or return address, it just said, 'John and Yoko.' They thought it was a piece of fan mail and they opened it up and it was a typed unsigned note that said, 'You and your Jap tart think you're hot shit,' and John was wounded by it. He loved her and couldn't understand why people would hate her, and Paul came into the living room and he says, 'Oh, I just did that for a lark!' The letter was from Paul, and John looked at him and that look said it all, 'Do I know you?'"
