Al Gore served as United States vice president from 1993 to 2001 and later became closely associated with climate campaigning, including the 2006 film An Inconvenient Truth. That stiff, serious public image made him a recurring target for parody on The Simpsons, the long-running animated sitcom that began in 1989 and built its humour around Homer Simpson and his family. Clips of its cartoon Gore circulated online as shorthand for a boring, self-serious speech, and soundboard users kept sharing it because the monotone delivery works without the original scene.
