• How I Met Your Mother: The great and terrible Jennifer Lopez is set to guest star on HIMYM this March as Anita Appleby, "a no-nonsense author of self-help books that teach women how to train men into relationship machines through the power of denial." Anita and Barney will go head-to-head over his bad behavior toward women. (This has been a hell of week for HIMYM, don't you think?)
Plus, which at-risk Mad man did we discover is definitely returning for season four?
• Lost: Not as Island-minded as rest of the world? Have trouble remembering who so-and-so is, and why what's-her-face hates that other guy on Lost? No? Of course not! Still, there's a fun little chart on the Interweb today that maps out each character and their connections, and even the most knowledgeable Lost fan will benefit by taking a peek.
• Jersey Shore: The Jersey Shore cast might deign to come back to work on their hot mess hit show if MTV agrees to pay them $10,000 an episode. In other news, the sky turned orange yesterday and the planet is spinning backward.
