While doing some google searches to find the correct date, I learned that Justice Stevens attended Game 3 of the 1932 World Series between the Cubs and Yankees. This was the game where Babe Ruth allegedly called his home run shot. And he is 100% positive that I can remove the word allegedly from that sentence.
I always enjoyed the subject of American History in school and while it's hard for me to think of things that happened in my lifetime as "history", Justice Stevens has definitely made an impact with some of his rulings. Here's an interview he did with 60 Minutes right before retiring. It's a typical interview piece that mostly focuses on his youth and career but he does mention the Babe Ruth incident and you can see some of the Cubs stuff he has in his office, including a Mark Prior jersey. He seems like such a smart, down to earth guy that would be fun to have a beer with and talk Cubs even in his 90s. Sorry about the ad before the video, couldn't find another one.
