Photo: Jimmy Kimmel Live via YouTube John Lithgow wrote a poem for Stephen Colbert this week. That’s a little too hagiographic, even for this finale era of The Late Show. It does seem like Colbert isn’t entirely comfortable with the fawning he receives — either from guests or the “Stephen! Stephen!” chanting audience. Watching guest after guest, I’ve come to understand that this farewell to Colbert is a chance for deeply famous people to fangirl out a bit, something they so rarely get to do.
