On Buffy the Vampire Slayer (8 p.m., WB), Riley's frat house is possessed by an evil spirit that gets more powerful every time Riley and Buffy do the nasty. Scientific American Frontiers (check local times, PBS) celebrates its 10th anniversary with a look back at some of the greatest scientific achievements of the past decade. On Angel (9 p.m., WB), Faith surfaces in L.A., where she goes to work for (who else?) the demonic law firm of Wolfram and Hart.

Specials
It's the '80s all over again as former Mrs. Mike Tyson Robin Givens and former "Cosby Show" kid Tempestt Bledsoe team up for the cable movie The Expendables (9 p.m., USA), in which they play convicts who are given a chance at freedom if they take part in a dangerous undercover mission. And while we're on the subject of women with shady pasts, Court TV presents the nostalgic documentary Tonya Harding: Ice Follies (10 p.m., Court TV), a cautionary tale about a girl, a dream and a lead pipe. Harding, Robin Givens and Faith the Slayer -- now that's a "Charlie's Angels" remake I'd pay money to see.
