President Barack Obama has exercised his revenge after weeks of attacks from his would-be Republican challenger Donald Trump, joking that the billionaire businessman could bring change to the White House, transforming it from a stately mansion into a tacky casino with a whirlpool in the garden.
With Mr Trump in attendance, Mr Obama used the White House Correspondents' Association annual dinner to mock the reality TV star's presidential ambitions.
Mr Obama said Mr Trump has shown the acumen of a future president, from firing actor Gary Busey on a recent episode of Celebrity Apprentice to focusing so much time on conspiracy theories about the President's birthplace.
After a week when Mr Obama released his Hawaii birth certificate, he said Mr Trump could now focus on the serious issues, from whether the moon landing actually happened to "where are Biggie and Tupac?"
"No one is prouder to put this birth certificate matter to rest than 'the Donald'," Mr Obama said, referring to Mr Trump's claims the same day that he was responsible for solving the issue.
For Mr Trump's decision to fire actor Busey instead of rock singer Meat Loaf from his TV show earlier this month, Mr Obama quipped: "These are the types of decisions that would keep me up at night. Well handled, sir."
Mr Trump chuckled at some of the earlier jokes, but was clearly less amused as comedian Seth Meyers picked up where the President left off.
"Donald Trump often talks about running as a Republican, which is surprising," said the Saturday Night Live actor, entrusted with providing some of the comedy for the evening. "I just assumed he was running as a joke."
Trump stared icily at Meyers as he continued to criticise the real estate tycoon.
Other possible Republican presidential hopefuls in attendance were former Utah Governor Jon Huntsman, Representative Michele Bachmann and former House Speaker Newt Gingrich. And stars such as Sean Penn and Scarlett Johansson also were among the 3,000 people who attended.
