Jimmy Kimmel welcomes David Letterman back to the world of late-night TV! Letterman is about to be honored with the Mark Twain Prize. There is even more good news,as Dave prepares for his new Netflix show. Fuzzy-faced Dave, who fancies that viewers might think Jimmy is talking with “an aging vagrant,” reveals what he misses most about late-night, and tells stories about life after the show. A moving anecdote about a prank gone horribly awry after Dave gifted Conan O’Brien with a certifiably insane horse – is a lesson we can all take to heart.
