Comedian-in-Chief: Obama Breaks Bread with White House Correspondents Finally tonight we've come to washington for that dinner that comes around once a year, the white house correspondents' dinner, the president and the reporters who cover him and try to ask him the tough questions all year long. This is typically the night he gives it back to us. With a healthy dose of humor and surprises on the guest list tonight, too. The first white house correspondents dinner in 1920. For years it was all men until president jfk said he would not attend a dinner unless the ban helen thomas had provided him to make the change. Presidents have poked fun of themselves. Bill clinton on his way out. The clock is running out on the republicans in congress, too. I feel for them. They've only got seven more months to investigate me. That's a lot of pressure. Reporter: George w. Bush had us seeing double. Distinguished guests, ladies and gentlemen, here I am. Here I am at another one of these dang press dinners. Last year president obama with a preview of what was to come. In my first term I sang al green. In my second term I'm going to young jeezy. In recent years along with the humor all the glamor has become a hollywood who is who. This sear gloria are from modern family is back. Barbra streisand is here. Conan o'brien, he is the host tonight. Today we learned of someone else on the guest list. &#9834; yes, psy is on the list all in one room to poke a little fun at the president and the press. Tonight both sharing the punch line.
