Comedian Conan O'Brien took a break from his late-night show, "Conan," to join President Obama in Washington, D.C. 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."

Read on to see Conan O'Brien's jokes from the 2013 White House Correspondents' Dinner.

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."

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."

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.

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!"

Tittering at the Twitter Crowd

While Republicans, the president, Congress and media organizations all took hits, the reporters themselves didn't escape Conan's sharp tongue either.

"If any of you are live-tweeting this event, please use the hashtag '#incapableoflivinginthemoment,'" O'Brien said to laughter and applause. "Yes, also to any U.S. senators here tonight, if you would like to switch either your dessert or your position on gay marriage, please signal a waiter."
