Tonight, David Letterman's storied run as a talk show host will come to an emotional end with the Foo Fighters and a ton of other surprise guests in tow. But before taping could begin, one last audience had to line up outside the Ed Sullivan Theater. As you'd expect, the crowd was filled with superfans who we spoke to on the heels of their favorite late-night talk show host's departure. They shared their favorite moments from Letterman's run, what adult responsibilities they missed to be there today, and a farewell message for the comedian.
