Saturday at the 2013 White House Correspondents' Dinner. Two hours or so before the festivities began, he sent out a picture of himself behind a podium, sporting a Boston Red Sox hat. "Just rehearsed my routine to an empty ballroom at the Washington Hilton," the comedian tweeted. "The one guy unfolding chairs loved it."

 ABCNEWS.com No Tickets for Joe Throughout the night, O'Brien took shots at Vice President Joe Biden, who also appeared earlier in the night in a video mashup of his gaffes. "It's an honor to share this stage with the president," he said at the start of his set. "When you think about it the president and I are a lot alike. We both went to Harvard. We both have two children and we both told Joe Biden we didn't have extra tickets for tonight's event." 
  
 ABCNEWS.com Conan Has the Hots for LaHood? The comedian went on to point out another way in which he felt he could identify with President Obama. "Like the president, I too, recently got in some hot water by talking about a public official's good looks," O'Brien confessed. "It was the time I wouldn't shut up about that stone cold fox, Secretary of Transportation Ray LaHood." "Oh man," he added. "I like the cut of his gib." 
  
 ABCNEWS.com Questioning Chris Christie Biden wasn't the only reoccuring character in O'Brien's jokes. New Jersey Governor Chris Christie took a few hits as well. "I'd like to acknowledge that earlier this evening, there was some confusion with the seating chart. For a moment, someone accidentally sat Governor Chris Christie with the Republicans. That was awkward, and I apologize," he said. Christie seemed to take it in stride, laughing alongside his host, Arianna Huffington. 
  
 Brendan Smialowski/AFP/Getty Images Obama's Overabundant Emails In the wake of the election, O'Brien centered several jokes around the president's entering his second term, including one that hit on the organziation grown out of his campaign, now called Organizing for Action. "I have a question, and I think some of you also have this question," he told the president. "It's been several months since you were reelected, sir, so I'm curious, why are you still sending everyone five emails a day asking for more money?" "You won," he reminded Obama. "Do you have a gambling problem we don't know about?" "Did you put it all on Gonzaga?" he asked, a reference to the president's NCAA March Madness college basketball bracket. "You did, didn't you? He did!" ||||| Former vice presidential nominee Sarah Palin came out with a strongly worded tweet condemning the White House Correspondents' Association Dinner, calling its participants "assclowns" after the dinner concluded.

 “David Axelrod now works for MSNBC, which is a nice change of pace, since MSNBC used to work for David Axelrod.” 
  
 “And then there’s the Easter Egg Roll, which is just supposed to be a nice event with the kids. I got out on the basketball court, took 22 shots, made 2 of them. That’s right, 2 hits, 20 misses. The executives at NBC asked, ‘What’s your secret?’” 
  
 ”One thing [the Republican Party] agrees on is the need to do a better job of reaching out to minorities. And look, call me self-centered, but I can think of one minority they can start with.” [Raises his hand] Think of me as a trial run, see how it goes.” |||||
A: 
This year's White House Correspondents' Dinner saw laughs mixed with reflection on tragedies in Boston and Texas. President Obama took shots at the GOP and the media—not to mention himself. Among his best jokes, via Politico and the Los Angeles Times: "Some folks still don’t think I spend enough time with Congress. ‘Why don’t you get a drink with Mitch McConnell?’ they ask. Really? Why don’t you get a drink with Mitch McConnell?" On the changing world of the media: "I remember when Buzzfeed was just something I did in college at 2am." "These days I look in the mirror and I have to admit, I’m not the strapping young Muslim socialist I used to be." And from Conan O'Brien, per ABC News: "Like the president, I too, recently got in some hot water by talking about a public official's good looks ... It was the time I wouldn't shut up about that stone-cold fox, Secretary of Transportation Ray LaHood." "When you think about it, the president and I are a lot alike. We both went to Harvard. We both have two children. And we both told Joe Biden we didn't have extra tickets for tonight's event." "To any US senators here tonight, if you would like to switch either your dessert or your position on gay marriage, please signal a waiter." Business Insider notes that not everyone was yukking it up: Sarah Palin tweet-bashed "these DC assclowns" as "pathetic." But the president also had some serious words: "As we gather here tonight, our thoughts are not far from the people of Boston, the people of West, Texas, and in the Midwest there are some people coping with some terrible floods," he noted, adding to media guests: "If we’re only focused on profits, on ratings, and on polls, we are contributing to the sense of cynicism that’s out there right now."
