This episode makes our list for a few reasons, the biggest of which is that it guest stars Robin Williams. His memorable appearance aside, it shows the unbreakable bond between Elliot Stabler and Olivia Benson, when Benson is thrown into peril and Stabler must do everything in his power to save her. "Authority" shows a particular set of psychological tricks that are horrifying to consider as Stabler accidentally makes things worse for Benson. Williams was noninated for an Emmy for his appearance, which may haunt you even more than One Hour Photo.
