Why it's on the list: "Nightshifter" proves that a standalone doesn't have to be funny to make it's mark. This is a white knuckling, action thrill ride from beginning to end. It's easily one of the best episodes of the series, let alone just another Ben Edlund quirky standalone. It's fun, it's breathtaking, it's a situation that with every minute unravels before our very eyes. How can Sam and Dean possibly come out of this alive? Plus, who doesn't love a good old fashioned mandroid conspiracy theory?
Favorite scene: Duh. You know it. We all know it. We to this day talk about it because it is the best scene ever! As the FBI looks for Sam and Dean in the bank, two swat team members are seen entering a parking garage right when the slow open on Styx's "Renegade" comes on in the background. It's Sam and Dean in clever disguise. They slow down, approach the Impala, get in, and take their helmets off, clearly shaken by the entire ordeal. "Hangman is coming down from the gallows and I don't have very long..." Three beats and now it's time for Dean's infamous line. "We are so screwed." Kick in the Tommy Shaw yell from the song and the Impala peels away as the rocking portion of the song follows them out.
