The White House Correspondents’ Dinner has produced viral moments that were funny, cringeworthy or undeniably tense and that endure across social media. Presidents Ronald Reagan and George H.W. Bush welcomed jokes, while George W. Bush brought some of his own. Comedians Stephen Colbert and Michelle Wolf created tension in the room. And President Barack Obama's mockery of Donald Trump set the stage for the reality TV star's move into politics. The dinner began a few years after World War I. Some years were forgettable and relegated to C-SPAN archives.
