Washington ( CNN ) -- President Barack Obama made light of the serious -- a Secret Service scandal and lavish spending at a government conference -- and the inconsequential -- the graying of his hair -- at the annual White House Correspondents ' Association Dinner on Saturday night . And he even made time for business tycoon Donald Trump , whom Obama kidded at last year 's dinner about pushing the president to release his long-form birth certificate . `` We gather during a historic anniversary . This weekend last year , we finally delivered justice to one of the world 's most notorious individuals , '' Obama said to a packed ballroom at the Washington Hilton . A photo of Trump was shown , rather than that of slain al Qaeda leader Osama bin Laden . Obama then went back even further in time . `` Four years ago , I was in a brutal primary battle with Hillary Clinton , '' Obama said . `` Four years later , she wo n't stop drunk texting me from Cartagena , '' a reference to the city where Secret Service agents allegedly consorted with prostitutes . He then pointed out photos of his hair four years ago , and in 2012 , showing it had grayed considerably . `` Four years from now I will look like this , '' he said to laughs as a photo of actor Morgan Freeman was shown to the audience of more than 2,500 . Journalists and news organizations were well-represented at the affair and they brought famous faces in tow . Among those who dazzled on the red carpet Saturday were Claire Danes , Elizabeth Banks , Paul Rudd , Sigourney Weaver , Eva Longoria , Viola Davis , Kerry Washington , Rachel Zoe , Goldie Hawn and Josh Hutcherson . The annual gala , also known as the `` Nerd Prom , '' raises money for journalism scholarships . The president , speaking before comedian Jimmy Kimmel , made light of a General Services Adminstration conference in Las Vegas that cost more than $ 800,000 . `` Look at this party . We have men in tuxes , women in gowns , fine wine , first-class entertainment . I was relieved to hear it was not a GSA conference , '' Obama quipped . He even chided Kimmel , star of ABC 's `` Jimmy Kimmel Live ! '' `` Jimmy got his start on the 'Man Show . ' In Washington , that is what we call a congressional hearing on contraception . '' Kimmel , who took the stage following the president 's monologue , hit back . `` Remember when the country rallied around you in the hopes of a better tomorrow ? '' Kimmel asked . `` That was hilarious . '' Kimmel said there was a term for `` guys like the president , '' and it was n't two terms . Nobody in the room was safe from Kimmel 's barbs , which he fired at politicians , journalists , celebrities and corporate executives in attendance . Kimmel praised Michelle Obama 's work to combat obesity with her health initiative . The comedian then pointed out rotund New Jersey Gov . Chris Christie to the first lady . `` Look , it 's Chris Christie . Get him , '' Kimmel said . Kimmel then took aim at Newt Gingrich 's weight . But Kimmel 's fat jokes fell , well , flat with the former House speaker . The dinner was Obama 's fourth as president . It has been a ritual in Washington since 1920 , when it was first held to boost communication between the press and the president , according to the association 's website . It was open only to men until 1962 , when President John F. Kennedy said he would not attend unless women were invited . Speaking of women , first ladies have been known to get in their own digs . In 2005 , Laura Bush said friends went out one night to see male strippers after Bush , `` Mr . Excitement , '' was typically fast asleep at 9 p.m. First lady Hillary Clinton was featured in a video clip shown at the 2000 dinner . Seated in a limousine , she told the camera , `` I wish I could be here more , but I really think Bill has everything under control . '' The president ran out to the White House driveway , yelling after the departing car , shouting , `` Wait ! Wait ! You forgot your lunch ! '' While the dinner is notorious for its bawdy humor , the president took a moment to remember the sacrifices of journalists Anthony Shadid and Marie Colvin , who both died while covering the conflict in Syria .
Jimmy Carter gives as good as he gets . The president makes mention of the Secret Service , GSA etc . He also makes references to Donald Trump and his own hair .
