Some men will never learn. In 1973, tennis great Bobby Riggs came out of retirement to announce that women’s tennis was “so far beneath” men’s tennis and that even at age 55, he could beat any female player, especially 29-year-old, five-time Wimbledon champion, Billie Jean King. At first, King declined Riggs’ challenge. Top-ranking pro Margaret Court took her place, only to lose terribly. Riggs publicly denigrated all female players, prompting King to change her mind and accept his bet. On September 20, 1973 the rivals met at the Houston Astrodome to duke it out on the court (the prize was $100,000). King was carried into the arena by four bare-chested men while Riggs rode in a rickshaw driven by scantily clad models. They exchanged gifts (a lollipop and a live pig), and then started the match. King beat him, and beat him good. Was Riggs too old? Too cocky? Too out-of-shape? Perhaps Billie Jean King was just better.
