The humorous, 1,000-plus word speech President Barack Obama is set to give at Saturday's traditional Correspondents Dinner is being prepared by numerous "Hollywood joke writers, White House lawyers and other advisors," United Press International reported.

Actor Zach Galifianakis, presidential speechwriter Cody Keenan and David Litt -- a former intern at the Onion who has since ascended to a deputy White House speechwriter -- are all part of the effort. And the litany of mostly self-deprecating jokes always marks a departure from the often stale D.C. rhetoric.

"Not every world leader would expose himself like that," Litt noted.

So what does Obama look for in his Correspondents' Dinner address?

"His general interest is making sure it's funny," Keenan said. "What's great about it is it gives you a chance to point out all the absurdities of Washington -- and there are plenty of them."

Saturday night's event, which will once again take place at the Washington Hilton, features a guest list that includes "celebrities who only play political powerhouses on TV," such as Kerry Washington from "Scandal" and Téa Leoni from "Madam Secretary," People pointed out.

But according to "Nerd Prom," filmmaker Patrick Gavin's documentary about the event, most stars in attendance cannot actually name a single White House correspondent.

"When asked to identify their favorites, Gary Cole hems and haws, Matthew Morrison laughs uncomfortably and Patrick Duffy stalls," the magazine detailed.

The gala put on by the White House Correspondents' Association has come under much fire recently, especially after New York Times Magazine national correspondent Mark Leibovich made it the focus of his 2013 bestseller "This Town."

"I think that it's morphed into this extravaganza of more than two dozen pre-parties and after parties, and we have to ask ourselves: What are we celebrating exactly?" the author said on ABC's "This Week" about last year's event, according to Politico.

Nevertheless, many news organizations, including Vanity Fair and MSNBC, will once again spend six-figure sums to host politicians and celebrities at numerous events surrounding the dinner, Politico noted.
