A new "Simpsons" is one of tonight's highlights, and so is an old -- as in 3 years old -- "Seinfeld."
* "The Byrds of Paradise" (8-9 p.m., WJZ, Channel 13) -- Some of the plot lines on this series have ebbed a bit, so tonight the writers are trying to go with the flow: The Byrds of Hawaii, along with everyone else on the tropical island, make preparations when a tidal wave, or tsunami, heads in their direction. Have I given away too much of the story? So tsu me. ABC.
* "Christy" (8-9 p.m., WBAL, Channel 11) -- To teach her backwoods students the absurdity of feuding, Christy (Kellie Martin) pulls out Shakespeare's "Romeo and Juliet" and teaches it as an object lesson in how quarrels between families can end tragically. The risk inherent in this particular lesson plan, of course, is that her students will end up being Bard to death. CBS.
* "The Simpsons" (8-8:30 p.m., WBFF, Channel 45) -- Not too long ago on "The Simpsons," Homer had to wrest his son from the influence of a well-meaning foster friend whose relationship with Bart was, in many ways, closer than the one between Bart and Homer. A similar dilemma surfaces tonight, but this time the elder role model is really old: It's Mr. Burns, the crotchety old rich guy who virtually owns Springfield, and who in tonight's episode sets up Bart as a potential heir to his fortune. Fox.
* "Seinfeld" (9-9:30 p.m., WMAR, Channel 2) -- I find these very old episodes of "Seinfeld" -- before it was a cult success, much less a mainstream hit -- particularly absorbing. This is when the writers and performers were feeling their way, doing things largely for themselves, and having a good time. This is the one about the overdue library book, and it's just fine. NBC repeat.
* "Frasier" (9:30-10 p.m., WMAR, Channel 2) -- Frasier and his dad, and Daphne and even Niles, pile into a recreational vehicle for some alleged recreation: driving to Mount Rushmore. You know what happens when you get behind schedule on that particular trip? You Rushmore. Kelsey Grammer, John Mahoney, Jane Leeves and David Hyde Pierce star. NBC.
* "Holocaust" (8-10 p.m., Family) -- This is the conclusion of the landmark 1978 NBC miniseries -- and the one in which Meryl Streep and James Woods, among others, give heart-wrenching performances. While bestowing all that credit on "Schindler's List," remember that TV did this drama, and did it very well, 15 years earlier.
