The most lovely, adorable person ever, Emma Watson, stopped by The Late Show with David Letterman to talk about the Harry Potter and The Deathly Hallows Part 2 premieres and her costar Daniel Radcliffe. Of course, Dave rattles her a bit when he asks her about her relationship with "controlled substances," but he gets to the bottom of this mystery.
Jimmy Fallon continues his late night awesomeness by challenging Kid Rock to a game of horseshoes while drinking Badass beer. Clearly, the beer and banjo music aren't helping, but it's fun all the same.
Denis Leary stopped by The Daily Show to talk to his old buddy about the last season of Rescue Me and apparently his character is being inducted into the Smithsonian. But to be honest, the best part of all of this is when Leary calls Stewart out. Of course, Jon fires back (all in good fun). And this is why watching comedians who are friends in real life conduct a talk show interview is so wonderful.
