You know, I have never seen any of these shows.  They are in my Netflix queue, on my Amazon Wishlist I've even fingered them a few times at various stores, but I've never seen them.
 
Now, just about anything else the Sedaris Family does is an indicator enough that I NEED to experience it.  But, I have never gotten to these particular morsels.  But, some day, I will.  
 
BTW, if you likde Davis Sedaris, try 
Augusten Burroughs.  I haven't read the latest collection of short stories yet, but I have read his 2 memoirs and love them both for their hilarity and insanity.  But, be warned, while David's mother is a bit crazy, Augusten's mother is certifiable.  It made me appreciate his humor all the more.
