Check out this article on the history of the US Presidents in relation to the Olympics (as I'm watching Olympics right now). Did you know Kennedy tried to help Detroit get the Olympics? I thought that was cool (you can watch the video if you follow the link):
In 1963, President Kennedy taped a message supporting Detroit’s bid to host the Olympics, which ultimately went to Mexico City. (To this day, Detroit is the only city to make an Olympic bid seven times and never get it.) Although that was the only time Kennedy got involved in the Olympics, he often stressed the importance of physical fitness. “We do not want our children to become a generation of spectators,” he once said. But the biggest athletic champion in his family was his sister Eunice, who founded the Special Olympics in 1968.
