He was introduced with the song "Real American" with shots of the certificate cut into a South Park-style montage, Politico reported. The president also said he really wanted to put the issue of his birth to rest -- and showed a brief clip from the Disney cartoon "The Lion King."
Obama also took aim at Donald Trump, who has become of the country's best-known "birthers" in the past few weeks and a possible Republican candidate for president next year.
"Now, I know that he's taken some flak lately, but no one is prouder to put this birth certificate matter to rest than The Donald," Obama said. "And that's because he can finally get back to focusing on the issues that matter, like, 'Did we fake the moon landing?' 'What really happened on Roswell?' And 'Where are Biggie and Tupac?'"
Obama also took aim at Rep. Paul Ryan, R-Wis., saying he missed the dinner because his proposed budget has "no room for laughter." And he dismissed actor Matt Damon's criticisms of his job performance by remarking he has seen "The Adjustment Bureau."
The president also showed a clip of bloopers by Vice President Joe Biden, saying that when his teleprompter malfunctioned he turned for help "to a man who never lets prepared remarks stand in his way."
