VIDEO: Anderson Cooper Suffers Uncontrollable Giggling Fit (Again) on AC360

Remember when Anderson Cooper suffered from an uncontrollable giggling fit on Anderson Cooper 360 last August? Well, it happened again.
This time, cause of laughter was the little-known Polish American holiday, Dyngus Day, which is celebrated after Lent. During Cooper's "RidicuList" segment, he mentioned a common Dyngus Day tradition that involves boys sprinkling girls with water, and girls retaliating by striking the boys with a "pussy willow" branch. You can guess which of the two triggered Cooper's laughing fit.
Check out the segment in the clip below at the 1:30 mark.

After the segment aired, Polish organizations spoke out about being offended by Cooper's comment, Deadline reports. During his laughing spell, Cooper said, "This is so stupid."

Cooper has since apologized, noting that he wasn't diminishing the holiday, but was rather making fun of himself. "I am concerned to hear that some people believe that I called Dyngus Day celebrations 'stupid' or in any way criticized this holiday. I did not," he said. "While in the midst of a silly giggle fit I said 'this is so stupid' in reference to my inability to stop laughing... I am genuinely sorry if I offended anyone by the lighthearted tone of the RidicuList."Were you offended by Cooper's laughter?
