Queen Elizabeth II Addresses a Joint Session of Congress.

Washington, DC. 5-16-1991 Queen Elizabeth II made history by becoming the first British monarch to address a joint session of Congress, opened her remarks by poking fun at herself and ended with a sure-fire crowd pleaser: "May God Bless America." She received three standing ovations and was interrupted by applause several more times during a 15-minute speech. The diminutive queen began with a reference to the fact that only the brim of her purple-and-white hat was visible to television audiences (Photo by Mark Reinstein/Corbis via Getty Images)
