Anderson Cooper added himself to his RidicuList segment last night after he was chastised for breaking out in a fit of giggles while describing Dyngus Day, a Polish-American holiday, during Tuesday’s AC360.

Cooper clarified that he didn’t put Dyngus Day itself on the RidicuList, but rather anyone who missed out on the holiday. He also explained that the “This is so stupid” remark he made during the giggle episode was directed at his inability to hold it together, not the holiday.

“I said it was stupid because it’s stupid that a grown man giggles like a 13-year-old girl meeting Justin Bieber for the first time,” he said, drawing the same comparison he used in August after breaking out in laughter while discussing Gerard Depardieu’s airplane urination incident.

To prove just how seriously he took his hysteria, Cooper invited Eddy Dobosiewicz, the co-founder of Buffalo’s Dyngus Day Celebration, to his show to comment.

“Although you have upset many, many people here in Western New York and throughout the land, we accept your apology, Mr. Cooper,” said Dobosiewicz, who then extended an invitation to Cooper to join in the Dyngus Day festivities next year, and asked him to become the first ever Pussy Willow Prince.
