Melissa McCarthy is the ultimate physical comedian, and she's even funnier through night vision. McCarthy hosted SNL on Saturday night, and in addition to making audiences re-live the horror of watching a sex scene with your parents, she brought her signature Stooge skills to a sketch about a horror movie test screening. Needless to say, she got a bit too jumpy during the jump scares.
