Buffy the Vampire Slayer (8 p.m., WB) and Angel (9 p.m., WB) rerun the November crossover two-parter in which Buffy and Angel have a day of bliss, thanks to a demon's curse that restores Angel's soul. In case you didn't get all the way to the bottom of the list of Emmy nominees, where they stash the writing nominations, "Buffy" creator Joss Whedon was nominated for best screenplay for a drama series for the "Hush" episode. He's in the company of writers for "The Sopranos" and "The West Wing"; both of those series are up for best drama, but "Buffy" is, of course, not. The academy threw "Buffy" a frickin' bone (in the words of Dr. Evil) with Whedon's nomination. But we'll take it anyway. Multinominated Frasier (9 p.m., NBC) repeats the one where a night at the opera leads Frasier's friends to think Martin is gay. Thurgood learns that he's a descendant of Thomas Jefferson on The PJs (9:30 p.m., Fox). Noah Wyle guests on Beggars and Choosers (10 p.m., Showtime) as a prolific TV writer-producer who might seem familiar to fans of "The Practice" and "Ally McBeal."
The new cable movie They Nest (8 p.m., USA) stars Thomas Calabro as a Maine doctor caught in a deadly cockroach invasion. And you thought he had problems on "Melrose Place."
