Stephen Farnsworth, a co-author of “Late Night in Washington: Political Humor and the American Presidency,” says: “It was a comforting collection of lighter fare before bed. It was for people who work second shifts in factories, people who just wanted a joke or two and a celebrity interview before they drop off. It was a cultural experience back in the days of Carson where you had one show that dominated above all and it had those moments that people would talk about the next day at work.”
