For some reason, I am fascinated and find the episodes of “Comedians in Cards Getting Coffee” to be laugh out loud funny.  Now, I am not a fan of Jerry Seinfield, and even less so of Tina Fey, but this one is great – http://comediansincarsgettingcoffee.com/tina-fey-feces-are-my-purview

I think it really is about the coffee and seeing these famous people doing normal things, and as it appears, being their true self, whatever we imagine or think that might be.  We see them in a natural setting, talking, and for the most part not trying to be funny, but observing, being open, and are funny because of that.
