Linoleum Knife 12/18/11: "Mission: Impossible - Ghost Protocol," "Sherlock Holmes: A Game of Shadows," "Alvin and the Chipmunks: Chipwrecked," "Carnage"

It's Dave and Alonso's 50th episode, and the president has initiated ghost protocol. So they've got lots to say about Agnes Moorehead, Joan Didion, a certain church with a lot of L.A. real estate, macarons and the banning of the word "bromance." Happy Holidays!
