Reagan was known to joke frequently during his lifetime, displayed humor throughout his presidency, and was famous for his storytelling. His numerous jokes and one-liners have been labeled "classic quips" and "legendary". Among the most notable of his jokes was one regarding the Cold War. As a microphone test in preparation for his weekly radio address in August 1984, Reagan made the following joke: "My fellow Americans, I'm pleased to tell you today that I've signed legislation that will outlaw Russia forever. We begin bombing in five minutes." Reagan's sense of humor was also observed by hundreds of Americans at Tempelhof U.S. Air Base June 12, 1987. While giving a speech celebrating the 750th anniversary of Berlin, a balloon popped in the front row. Without missing a beat, Reagan quipped "missed me", a reference to his previous assassination attempt in 1981. Former aide David Gergen commented, "It was that humor... that I think endeared people to Reagan."
