The Best SNL episodes ever?

Happy birthday, SNL!  For all the posts about SNL sketches here, I've never tried to list the best show of every season.  Nor will I now.  But here's 15 episodes that could be contenders for best of the season.  Note that I did not include any of Louis C.K.'s episodes because I haven't seen them all-the-way through, which is awful.  I have listed what I consider to be the best sketches from each episode (which is usually most of them); musical guest segments are not eligible.
