Saturday Night Live: A Very Gilly Christmas (8pm, NBC) - SNL has taken one of my all-time least favorite characters and built an entire Christmas special around her. If you're sick of Kristin Wiig's Gilly, as I am, record this special and fast forward through the Gilly bits, because you don't want to miss other classic SNL holiday skits, such as Alec Baldwin hawking his Schweddy Balls on NPR. Baldwin and Steve Martin both appear to introduce classic sketches.
The Mentalist (10pm, CBS) - During an investigation into the murder of a baseball scout, Jane is hit on the head with a ball and has flashbacks to his childhood and memories of his father, played by Nick Chinlund.
Jersey Shore (10pm, MTV) - This reality show has taken on a life of its own. Tonight is the episode in which Snooki gets assaulted in a bar, but MTV is not showing the scene of Snooki getting punched in the face by a bar patron. They have standards.
