I'll always remember when I went to a baseball memorabilia show and stood in line for Willie to autograph my two baseballs. A guy in front of me said to him, "Sign it, Willie Mays 660.". Willie responded, "That's my number, my accomplishment, not yours. I'm not doing that." I brought my mother (who passed away in 2007) with me, and she stood before me, and he smiled when she approached him. She asked him if he'd kindly add his home run total to the ball. He smiled at her again, and he did. I still have the ball. 'Willie Mays 660".
