Community [NBC, 8 PM]
Pierce's mother dies and the group rallies around him in support. I don't think I've ever watched characters extend sympathy towards a Chevy Chase character before, so this might be riveting TV. Check back tomorrow for Christopher Rosen's recap.
Project Runway [Lifetime, 9 PM]
Designer Norma Kamali guest-judges in this oh-so-delicious-sounding episode: The remaining contestants must make a garment for good old Heidi Klum. I expect Teutonic terror of the highest order.
Jersey Shore [MTV, 10 PM]
With Angelina gone, the castmates are left to enjoy being alive. JWOWW and Snooki compromise with Sammi, Vinny goes back to girl-hunting, and The Situation starts to bother Snooki. Oh man. If their irritation mounts and the two smush, will we be forced to watch them make out again? A repeat of their hot tub dalliance from season one? Pray to your local guido god that it's a no.
Alien [TCM, 10 PM]
The ageless Sigourney Weaver fends off against her spaceship's ugly, enormous stowaway in this classic sci-fi/horror treat. The Oscar-winning special effects will gross you out in the most dated, lovable way possible. As usual, all hail Ridley Scott.
