As you've probably heard by now, Buffy the Vampire Slayer (8 p.m., WB) is moving to UPN next season, after the show's production company, 20th Century Fox, and the WB failed to come to terms on a price for keeping the show on the Frog. UPN announced last Friday night that it has signed a $102 million deal for 44 more episodes (two years) of "Buffy." The deal also calls for UPN to pick up "Buffy" companion show "Angel" for 44 episodes if it's canceled by the WB. The WB's last "Buffy" episode will air May 22. On tonight's "Buffy," Spike has a new girlfriend. Oh, wait a minute -- it's only a Buffybot. A woman with a master's in English lit is shackled to a gaggle of guys with half a brain among them on Chains of Love (8 p.m., UPN). On Angel (9 p.m., WB), Lindsay gets a new hand -- a real one. Sipowicz is accused of dissing a gay kidnapping victim on NYPD Blue (10 p.m., ABC). But he can't be a homophobe -- he can almost tolerate Gay John!
Cindy Crawford hosts InStyle: Celebrity Moms (8 p.m., NBC), a look at famous women who are apparently better moms than the rest of us just because they're famous. The joint "Frontline"/"Nova" report Harvest of Fear (9 p.m., PBS, check local listings) looks at the controversy over genetically engineered crops.
