The Scoobies have trouble adjusting to life after high school on a rerun of Buffy the Vampire Slayer (8 p.m., WB). The new animated series Sammy (8:30 p.m., NBC) stars David Spade (who is also the show's producer) as a TV star whose prodigal father (also voiced by Spade) returns when his son gets famous. It's got a cool cast (David Cross, Bob Odenkirk, Janeane Garofalo), but the fact that NBC postponed the premiere twice -- and it's August -- should tell you something. If you, like everyone else, were watching Jordan get kicked off "Big Brother" last Wednesday, you missed the premiere of Fox's intriguing reality series American High (9 p.m., Fox), about teens at a suburban Chicago high school. The first two episodes are repeated back-to-back tonight. President Bartlet must attend to delicate public relations matters involving the first lady and his daughter on a rerun of The West Wing (9 p.m., NBC). NYPD Blue (10 p.m., ABC) repeats the one where Baldwin gets turned on by a reporter (the hapless Elizabeth Berkley). Did you see where oft-naked "NYPD" star Rick Schroder addressed the Republican Convention last week? Ah, I'll never be able to look him in the ass again. If you missed it Sunday, catch the Sex and the City (11 p.m., HBO) rerun; it's one of the best episodes of the season so far, a meditation on following one's heart vs. one's brain, with a breathtaking surprise at the end.
