On a rerun of Buffy the Vampire Slayer (8 p.m., WB), Willow's spell causes Giles to go blind and Buffy and Spike to fall in love. Mary Magdalene is the subject of a new Biography (8 p.m., A&E). Will & Grace (9 p.m., NBC) reruns the one where Will is embarrassed by Jack's flaming behavior at the gym. Wesley shows what he's made of in a rerun of Angel (9 p.m., WB) in which he and Angel have to perform an exorcism on a possessed boy. In the new game show Don't Forget Your Toothbrush (10 p.m., Comedy Central), contestants compete in humiliating endeavors in hopes of winning a vacation (to where, "Survivor" island?). Mark Curry hosts. P.O.V. (check local times, PBS) presents "Butterfly," a documentary about environmental activist Julia Butterfly Hill, who lived in an ancient redwood tree for two years to protest the cutting down of old-growth forests. The critically acclaimed, viewer-detested Fox sitcom Action (10:30 p.m., FX) rises again on cable. FX is airing all 13 episodes of the scathing, potty-mouthed parody of Hollywood movers and shakers. (Fox aired only eight episodes in the show's original run.) Jay Mohr stars as a ruthless studio exec whose biggest problem is that he's not ruthless enough; Illeana Douglas plays his muse and confidante, a former child star turned hooker.
Can 25 million Blockbuster customers be wrong? That's just a rhetorical question.
