President Obama will make his debut as comedian in chief when he appears at the White House Correspondents' Association Dinner on Saturday.
The annual gala is like prom night for Washington's media elite, and this year's guest list features a veritable stampede of celebrity hangers-on, including Ashton Kutcher, Demi Moore, Ben Affleck, George Lucas, Sting, Whoopi Goldberg, Julia Louis-Dreyfus, Eva Longoria Parker, and naturally, Kevin Bacon (see the White House Correspondents Weekend Insider blog for a complete list of who's coming to dinner).
Comedian Wanda Sykes will be the featured entertainer at this year's dinner, but all eyes will be on Obama as follows in the footsteps of his predecessors by performing his own comedy shtick.
To get you primed for this year's festivities, here's a look back at memorable moments from past White House Correspondents' Dinners, including George W. Bush conducting the U.S. Marine Band, Stephen Colbert's legendary Bush roast, Laura Bush's "Desperate Housewife" routine, and Bill Clinton's "Final Days" farewell video.
