The October 22 episode of Saturday Night Live, hosted by Tom Hanks, was one of the best in years, from the cold open, to Black Jeopardy!, to David S. Pumpkins, and this Halloween digital short with Cecily Strong, Aidy Bryant and Vanessa Bayer was no exception. It actually managed to be frightening... in how well it depicted how the best laid plans of mice and BFFs go awry once they come into contact with booze and sexy costumes. A Girl's Halloween is like a campfire ghost story, but for 20-somethings fresh out of college in the big city.
