President Obama tossed out a round of zingers at the annual White House Correspondents' Association dinner on Saturday to a crowd of A-list celebs and journalists. He got some laughs before he even hit the podium by opening his set with a fake "hot mic" moment, pretending to trash talk guests while backstage. During his nearly 17-minute monologue, the president covered a range of topics from "drunk" texts from Hillary Clinton to his competition in the presidential race.

When it came to Mitt Romney he said, "We both have degrees from Harvard. I have one, he has two. What a snob!" That one got a big thumbs up from former Republican presidential candidate Rick Santorum who was in the crowd.

Obama cracked one-liners at his own expense, too, venturing into the always awkward "about-that-time-I-was-given-dog-meat-as-a-kid" subject. Obama asked the packed house, "What's the difference between a hockey mom and a pit bull?" Note the subtle reference to Sarah Palin's classic line from the 2008 race. His response: "A pit bull is delicious."

While most joking in nature, Obama got serious for a moment to honor fallen journalists like Anthony Shadid of The New York Times and Marie Colvin of the Sunday Times of London who died while covering the news. “Never forget that our country depends on you to help protect our freedom, our democracy and our way of life,” said Obama.

The tradition goes back to 1914 and every president since then has attended the event.
