So the two episodes with audio commentary are Nature Calls and Into the Woods. Somehow I expected Nature Calls to be one of them, but why Into the Woods? I don't really remember that episode (though there were two woods episodes from the last two seasons... is this the one where Earl, Roy, and Robbie get stuck in a tarpit, or the other one?), but it doesn't seem to be very memorable. I would have rather there be commentary for Baby Talk, The Mating Dance (which I only remember seeing once), Variations of a Theme Park, Georgie Must Die, Steroids to Heaven, or Changing Nature.
