Anderson Cooper hosted Jimmy Kimmel on his CNN show Monday night to recap the 2012 White House Correspondents' Dinner.
Kimmel shared some jokes he had prepared but did not use. As Kimmel shared his extra, racy material, Cooper acknowledged that he couldn't actually laugh at any of them since he was a journalist. Cooper then told Kimmel that he probably didn't want to hear him laugh since he "giggles like a 12-year-old girl meeting Justin Beiber for the first time."
"Oh that's right!" Kimmel said. "Once you start laughing, it just never, ever stops."
"It never, ever stops," Cooper confirmed. "That is sadly true."
Cooper has collapsed into a fit of giggles on air more than once during his signature "RidicuList" segment. Last year, he grew hysterical when mocking French actor Gerard Depardieu, who was accused of urinating on a plane. He also lost control last month when he focused his "RidicuLust" segment on a little-known Polish-American tradition called Dyngus Day.
