What does Sammi do after Snooki and JWOWW give her valuable information about her horseplayin' housemate Ron Ron? We find out on tonight's Jersey Shore. Elsewhere on the tube: Project Runway gets intense, Big Brother gets results, and M. Night Shyamalan thrills you in the dark.
Big Brother [CBS, 8 PM]
Another houseguest hits the road. Matt and Enzo are both on the chopping block, but I have the feeling that self-described genius Matt, who told the house he needed to pay for his wife's "medical expenses," is so out tonight. Cut the Jonny Fairplay tripe, sir.
Project Runway [Lifetime, 9 PM]
Finally, a team challenge. The twelve remaining designers split into two squads to make collections that accommodate recent hair trends. Warlord Gretchen is sure to infuriate everyone, including -- here's hoping -- a teammate like frail AJ.
Jersey Shore [MTV, 10 PM]
Sammi confronts Ronnie after she reads the oh-so-anonymous letter from JWOWW and Snooki. (M)ike, (V)inny, and (P)auly bring two pairs of girls to the house, and both pairs don't know the other is there. Yep, it's a trope right out of Boy Meets World. Thanks, MTV.
Unbreakable [AMC, 10 PM]
M. Night Shyamalan's follow-up to The Sixth Sense enters a really rainy world where Bruce Willis gains superhuman strength after surviving a train wreck. Samuel L. Jackson is sufficiently creepy, and yes, prepare yourself for the twist ending.
