The White House Correspondents' Association annual dinner, begun in 1920, has become a Washington DC tradition and is usually attended by the President and Vice President. Thirteen presidents have attended a WHCA dinner, beginning with Calvin Coolidge in 1924. The dinner is held on the evening of the last Saturday in April. In recent years the featured speaker has often been a comedian, with the dinner taking on the form of a roast, especially of the President. This has been expanded to include short films involving the speaker or the President. Performers have included Nat King Cole, Dizzy Gillespie, Bob Hope, James Cagney, Barbra Streisand, Benny Goodman, Duke Ellington, Al Franken, Rich Little, Mark Russell, and Jay Leno.

Blah blah blah blah. That's what it says on Wikipedia at least. To summarize, this is where the press and the Prez get to blow off a little steam. Some years this goes well, they years they invite Steven Cobert, not so much. This was one of those strange, wacky times in which the goofy man with the "snarky monkey face" (to use the term of a GOP friend) delivered a dead-on dry humor stand up, and the master of strategy made some horrible tactical errors. On the dance floor.
