Why is "Stephen Colbert at the 2006 White House Correspondents' Dinner" trending?

Wikipedia Overview

On April 29, 2006, American comedian Stephen Colbert appeared as the featured entertainer at the 2006 White House Correspondents' Association Dinner, which was held in Washington, D.C., at the Hilton Washington hotel. Colbert's performance, consisting of a 16-minute podium speech and a 7-minute video presentation, was broadcast live across the United States on the cable television networks C-SPAN and MSNBC. Standing a few feet from U.S. president George W. Bush, in front of an audience of celebrities, politicians, and members of the White House Press Corps, Colbert delivered a controversial satirical routine targeting the president and the media. He spoke in the persona of the character he played on Comedy Central's The Colbert Report, a parody of conservative pundits such as Bill O'Reilly and Sean Hannity.
