FILE - In this Sunday, Dec. 2, 2012 file photo, reporter Anderson Cooper arrives at CNN Heroes at The Shrine Auditorium in Los Angeles. Cooper won't be in Buffalo, N.Y., to celebrate the city's heritage on Dyngus Day, a holiday that made his show's "Ridiculist" and left him giggling uncontrollably on the air last year.
