Paul Vasquez filmed the original Double Rainbow video in Yosemite National Park in January 2010, reacting with tearful amazement as two rainbows appeared over the valley. His repeated question about what it meant became an instant catchphrase, and the clip spread rapidly through YouTube, news coverage and remixes. Musical versions soon followed, turning his emotional narration into a song that kept the joke alive long after the original moment faded. It remains a shorthand for overwhelming, joyful surprise online.
