Conan O'Brien won't be performing at the White House Correspondents' Dinner until Saturday night, but he's already in the nation's capital, goofing around -- as shown in this photo he tweeted Friday.
"Practicing my opening 'Goofy Sunglasses' bit," he noted in the pic's caption.
This will be Conan's second time on the Dinner dais, having performed there originally in 1995, when President Clinton was in office. He told Politico that having the leader of the free world at his elbow was actually helpful: "Clinton was really laughing and he gets really red in the face when he laughs, and at one point he was hitting the table and I thought, 'This is great!' ... I definitely wouldn’t want to do my show every night with the president of the United States sitting next to me, chewing Nicorette. But it certainly amps things up."
The White House Correspondents' Dinner will be shown on several networks on Saturday night and O'Brien is expected to appear at 10 p.m. ET. Check back on TODAY.com for a roundup of the funniest moments!
