Anderson Cooper has another on-air giggle fit

(CBS News) It's happened again - Anderson Cooper erupted into a fit of giggles while hosting his CNN show, "AC360."

The host lost his composure Tuesday night during a RidicuList segment about Dyngus Day, a Polish American celebration marking the end of Lent.

Cooper kept his cool through the segment until footage from a Buffalo, N.Y., news report explained a few Dyngus Day traditions. The reporter said, "The quirky little rituals include boys sprinkling girls they fancy with water and the girls striking back with a tap from a pussy willow branch."

That last bit is  what had Cooper laughing uncontrollably.

This isn't the first time Cooper had a giggle fit on camera. Over the summer, he couldn't stop laughingduring another RidicuList bit, about French actor Gerard Depardieu's alleged public urination on an airplane.
