I enjoy listening to people talk in just about every way of the form, but especially in conversations. I ask a million questions just to listen to what people have to say(to the point where it's probably somewhat annoying at times). Listening to a good conversation is just as good as being involved in one for me. Comedians In Cars Getting Coffee is the best and purest form of celebrity conversation I think I've seen so far.
I'm a bit biased considering I already enjoy Seinfeld's humor, but I thoroughly enjoy listening to what always seems like good friends talking about the subjects they're talking about without having to put on a face for the camera (as in not having to put on a performance).
Season six just launched online with Julia Louis-Dreyfus (Veep, Seinfeld) as Jerry's first guest. I highly recommend going online and giving it a shot if you haven't already. The interviews are typically around 16 minutes long or so. The show is available online for free here:
