President Obama shared some words of wisdom in Washington last night, saying there are few things in life harder to find and more important to keep than love.

"Well, love and a birth certificate," Obama quipped at the White House Correspondents' Association dinner, poking fun at those who question his place of birth. "I happen to know that my approval ratings are still very high in the country of my birth." Obama was born in Hawai'i, but birthers question whether he was born overseas.

Obama also jabbed at Jay Leno, the comedian headlining the dinner. Obama dinged Leno as "the only person whose ratings fell more than mine."

The White House Correspondents' Association was formed in 1914 as a liaison between the press and the president. Every president since Calvin Coolidge has attended the dinner.

Mumford said there were no citations issued but Rich's security crew was asked to keep the noise down.
