MUST-SEE: "3rd Rock From the Sun" finale, 7 p.m., NBC. Ever since its arrival six years ago, "3rd Rock" has juggled several worlds. Partly a loud, silly comedy, it's also partly a clever satire, viewing the human condition through the eyes of people from another planet. Appropriately, the show is ending its run with an hour that continues to juggle the extremes. Some of it is just silly. Harry becomes convinced he's dating twins; Sally battles back when her boyfriend wants to be a muffin-maker instead of a cop. And some is quite good. Jane Curtin and John Lithgow, two skillful pros, paint a warm and funny picture of two longtime lovers.

"JAG," 7 p.m., CBS. Accustomed to ripping off real events, this show toys tonight with the John Kennedy Jr. death: Mac is ready to be a bride.

"Titus," 7:30 p.m., Fox. Another wedding arrives — maybe. Chris and Erin are supposed to marry.

"Frasier," 8 p.m., NBC. This classy comedy offers two new episodes. The first has troubles for two couples, Niles and Daphne and Frasier and the bittersweet Lana. The second sweeps the regulars away to a tropical vacation in Belize.

"Dharma and Greg," 8 p.m., ABC. Last week, Dharma's attraction to a handsome college professor (Kevin Sorbo) created a rift in her marriage. The troubles continue.

"Judging Amy," 9 p.m., CBS. In the season finale, a woman who is denied full custody of her daughter takes an extreme step.
