I've got two.
When Brooks was elected to the HOF he made appearances at Crown stations to give out and sign posters for fans. My wife and I went and he was so friendly. At the time he was announcing games with Chuck Thompson on tv and my wife told him he looks much better in person than he does on tv. Brooks said "Yeah, those tv cameras sure make you look fat!" Everybody there broke out laughing. We still have the posters hanging downstairs.
As a boy, the Orioles had a clinic at Memorial Stadium for Little Leaguers. Two kids from each area Little league got to go, and I was lucky enough to be one of the two from my league. Jim Gentile gave a talk on hitting and Milt Pappas on pitching. I was the tallest kid there, so Diamond Jim chose me to be his guinea pig on hitting. He knelt on one knee behind me and positioned my body, feet, arms etc. As he was doing so he said, "When I say OK, you go ahead and give it a rip." At one point, as he's getting me set up he inadvertently said, "OK, that ought to do it." Well, when I heard "OK" I swung as hard as I could. Gentile was barely able to duck out of the way. There was a stunned silence for a moment and I was mortified. One man there said "Wow, that would have made the front pages of the Sunpapers." And everyone let loose with a relieved laugh. Gentile was very nice to me, though. He said, "Don't worry about it, you did exactly what I told you to do. Good job. Now, lets try it again." Milt Pappas then talked about pitching and showed us various grips. He showed us the curve ball and told us not to try to throw a curve until we were 14 years old. Yeah, right. You know what all of us were doing as soon as we got home. Then we all had great seats for a Sunday afternoon ballgame. It was a great day. I don't know if they still do things like that.
