Best known as a comic actor in Airplane! and the Naked Gun movies, Mr. Nielsen passed away Sunday at the age of 84. Many of the tributes I've seen have referenced the Surely/Shirley joke from Airplane!, which was the inspiration for the Surely You're Joking headings I've put out this year. (I posted the trailer for Airplane! back in February to explain the headings.) Thanks for the laughs, Leslie.
